Lanthanum zirconate(ke kumu hoʻohālike La₂Zr₂O₇) ʻo ia ka laʻa-earth oxide ceramic i hoʻonanea i ka manaʻo e ulu nei no kona mau mea wela a me kemika. ʻO kēia keʻokeʻo, ka pauka refractory (CAS No. 12031-48-0, MW 572.25) he kemika inert a hiki ʻole ke hoʻoheheʻe ʻia i ka wai a i ʻole ka waikawa. ʻO kona ʻano kristal pyrochlore paʻa a me ka helu heheʻe kiʻekiʻe (ma kahi o 2680 °C) e lilo ia i insulator wela koʻikoʻi. ʻO ka ʻoiaʻiʻo, hoʻohana nui ʻia ka lanthanum zirconate no ka insulation wela a me ka insulation kani, e like me ka mea i ʻike ʻia e nā mea hoʻolako. ʻO kona hui pū ʻana me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka paʻa o ke kūkulu ʻana he mea pono hoʻi i nā catalysts a me nā mea fluorescent (photoluminescent), e hōʻike ana i ka versatility o ka mea.
I kēia lā, piʻi aʻe ka hoihoi i ka lanthanum zirconate i nā māla ʻoki. Ma nā noi aerospace a me ka ikehu, no ka laʻana, hiki i kēia seramika holomua ke kōkua i ka hana ʻana i nā ʻenekini māmā, ʻoi aku ka maikaʻi a me nā turbines. ʻO kāna hana ʻoi aku ka maikaʻi o ka thermal barrier, ʻo ia hoʻi, hiki i nā ʻenekini ke holo ʻoi aku ka wela me ka ʻole o ka pōʻino, hoʻomaikaʻi i ka pono o ka wahie a me ka hōʻemi ʻana i nā hoʻokuʻu. Hoʻopili pū ʻia kēia mau hiʻohiʻona i nā pahuhopu hoʻomau honua: ʻoi aku ka maikaʻi o ka insulation a me nā ʻāpana lōʻihi e hiki ke ʻoki i ka ʻōpala ikehu a me ka hoʻohaʻahaʻa ʻana i ka hoʻopuka ʻana i ke kinoea ʻōmaʻomaʻo i ka hana mana a me ka halihali. I ka pōkole, hoʻonohonoho ʻia ka lanthanum zirconate ma ke ʻano he ʻenehana ʻenehana kiʻekiʻe e hoʻopili ana i nā seramika holomua me ka hoʻomaʻemaʻe ikaika.
Hoʻokumu Crystal a me nā waiwai kī
Aia ka Lanthanum zirconate i ka ʻohana zirconate rare-earth, me kahi ʻano pyrochlore maʻamau "A₂B₂O₇" (A = La, B = Zr). Paʻa paʻa kēia anga aniani: ʻAʻole hōʻike ʻo LZO i ka hoʻololi ʻana mai ka lumi wela a hiki i kona helu heheʻe. ʻO ia ke ʻano, ʻaʻole ia e haki a hoʻololi paha i ka hale ma lalo o nā pōʻai wela, ʻaʻole like me kekahi mau seramika ʻē aʻe. He kiʻekiʻe loa kona wahi heheʻe (~ 2680 °C), e hōʻike ana i kona ikaika wela.
ʻO nā waiwai kino nui a me ka wela o La₂Zr₂O₇ nā:
● Haʻahaʻa haʻahaʻa thermal conductivity:ʻAʻole maikaʻi loa ʻo LZO i ka wela. He 1.5–1.8 W·m⁻¹·K⁻¹ wale nō ka La₂Zr₂O₇ mānoanoa ma 1000 °C. Ma ka hoʻohālikelike, ʻoi aku ka kiʻekiʻe o ka yttria-stabilized zirconia (YSZ). He mea koʻikoʻi kēia conductivity haʻahaʻa no nā uhi pale wela (TBC) e pale i nā ʻāpana ʻenekini.
● Hoʻonui wela kiʻekiʻe (CTE):ʻO kona helu helu o ka hoʻonui wela (~ 11×10⁻⁶ /K ma 1000 °C) ʻano nui. ʻOiai hiki i kahi CTE kiʻekiʻe ke hoʻoulu i ke koʻikoʻi like ʻole me nā ʻāpana metala, hiki i ka ʻenekinia makaʻala (ka hoʻolālā ʻaʻahu paʻa) ke hoʻokomo i kēia.
● Ke kūʻē ʻana i ka sintering:Kūʻē ʻo LZO i ka densification ma nā wela kiʻekiʻe. ʻO kēia "sintering resistance" e kōkua i ka uhi ʻana e mālama i kahi microstructure porous, kahi mea nui no ka insulation thermal.
● Paʻa kemika:ʻO ka Lanthanum zirconate ke kemika inert a hōʻike maikaʻi loa i ka pale ʻana i ka wela wela. ʻAʻole hiki ke hoʻololi a hoʻoheheʻe maʻalahi i nā kaiapuni paʻa, a ʻo kāna lanthanum paʻa a me ka zirconium oxides he mea maikaʻi loa ia.
● Haʻahaʻa oxygen diffusivity:ʻAʻole like me YSZ, LZO ka haʻahaʻa o ka oxygen ion diffusivity. I loko o kahi uhi pale wela, kōkua kēia i ka ho'ēmi ʻana i ka hoʻohemo ʻana o ka metala lalo, e hoʻolōʻihi i ke ola o nā mea.
Hoʻolilo kēia mau waiwai i ka lanthanum zirconate i mea hoʻokalakupua wela-insulating. ʻOiaʻiʻo, hōʻike ka poʻe noiʻi ʻo "ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa loa o ka LZO (1.5–1.8 W/m·K ma 1000 °C no kahi mea paʻa paʻa)" he mea pono mua no nā noi TBC. I loko o nā uhi hana, hiki i ka porosity ke hoʻohaʻahaʻa i ka conductivity ʻoi aʻe (i kekahi manawa ma lalo o 1 W / m·K).
Hoʻohui a me nā ʻano mea
Hoʻomākaukau maʻamau ka Lanthanum zirconate ma ka hui ʻana i ka lanthanum oxide (La₂O₃) a me ka zirconia (ZrO₂) i nā wela kiʻekiʻe. ʻO nā ʻano hana maʻamau e pili ana i ka hopena solid-state, ka hana sol-gel, a me ka co-precipitation. Ma muli o ke kaʻina hana, hiki ke hana maikaʻi ʻia ka pauka i loaʻa (no ka micron-scale) a i ʻole granulated. Hāʻawi nā mea hana e like me EpoMaterial i ka nui o nā ʻāpana maʻamau: mai nā pauka nanometer a i ka submicron a i ʻole nā ʻāpana granulated, a me nā ʻano spherical. He mea koʻikoʻi ka maʻemaʻe i nā noi hana kiʻekiʻe; Loaʻa ka LZO pāʻoihana ma 99.5-99.99% maʻemaʻe.
No ka mea paʻa ʻo LZO, maʻalahi ka mālama ʻana i ka pauka maka. He lepo keʻokeʻo maikaʻi ia (e like me ka mea i ʻike ʻia ma ke kiʻi huahana ma lalo). Mālama ʻia ka pauka a maloʻo a hoʻopaʻa ʻia i mea e pale ai i ka adsorption moisture, ʻoiai ʻaʻole hiki ke hoʻoheheʻe ʻia i ka wai a me nā waikawa. He mea maʻalahi kēia mau waiwai no ka hoʻohana ʻana i ka hana ʻana i nā seramika kiʻekiʻe a me nā uhi me ka ʻole o nā pōʻino kūikawā.
Ka Laʻana o ka Material Form: Hāʻawi ʻia ka Lanthanum Zirconate maʻemaʻe kiʻekiʻe o EpoMaterial (CAS 12031-48-0) ma ke ʻano he pauka keʻokeʻo i hana ʻia no nā noi hoʻoheheʻe wela. Hiki ke hoʻololi a doped me nā ion ʻē aʻe e hoʻolohe i nā waiwai.
ʻO ka Lanthanum zirconate (La2Zr2O7, LZO) he ʻano zirconate honua laha ʻole, a hoʻohana nui ʻia ia i nā kula he nui e like me ka insulation wela, ke kani kani, ka mea catalyst, a me nā mea fluorescent.

Nā noi i loko o ka Plasma Spray a me ka Thermal Barrier Coatings
ʻO kekahi o nā hoʻohana koʻikoʻi o ka lanthanum zirconate ma ke ʻano he topcoat i nā pale pale wela (TBCs). ʻO nā TBC he mau ʻāpana seramika multilayer i hoʻohana ʻia i nā ʻāpana mīkini koʻikoʻi (e like me nā lau turbine) e hoʻokaʻawale iā lākou mai ka wela loa. Loaʻa i kahi ʻōnaehana TBC maʻamau he ʻaʻahu paʻa metala a me ka topcoat seramika, hiki ke waiho ʻia e nā ʻano like ʻole e like me ka ea plasma spray (APS) a i ʻole electron-beam PVD.
ʻO Lanthanum zirconate ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ka paʻa e lilo ia i moho TBC ikaika. Ke hoʻohālikelike ʻia me nā pale YSZ maʻamau, hiki iā LZO ke kū i nā mahana kiʻekiʻe me ka liʻiliʻi o ka wela i ka metala. No kēia kumu, ua kapa ʻia nā haʻawina he nui i ka lanthanum zirconate "he mea moho hoʻohiki no nā noi TBC" ma muli o kona haʻahaʻa haʻahaʻa haʻahaʻa a me ke kiʻekiʻe o ka wela. Ma nā ʻōlelo maʻalahi, mālama ka lanthanum zirconate coating i nā kinoea wela i waho a pale i ka hale lalo ma lalo o nā kūlana koʻikoʻi.
He kūpono loa ke kaʻina hana hoʻoheheʻe plasma no La₂Zr₂O₇. I ka hoʻopuʻi ʻana i ka plasma, hoʻomehana ʻia ka pauka LZO i loko o kahi jet plasma a hoʻokuʻu ʻia ma luna o kahi ʻili e hana i kahi papa seramika. Hoʻokumu kēia ʻano hana i kahi lamellar, porous microstructure e hoʻonui ai i ka insulation. Wahi a ka palapala huahana, ua manaʻo ʻia ka pauka LZO maʻemaʻe kiʻekiʻe no "ka hoʻoheheʻe ʻana i ka wela plasma (ka uhi pale pale wela)". Hiki ke hoʻopaʻa ʻia ka hopena o ka uhi (e laʻa me ka porosity hoʻomalu a i ʻole doping) no nā pono ʻenekini a i ʻole aerospace.
Pehea e hoʻomaikaʻi ai nā TBC i nā ʻōnaehana aerospace a me nā ʻōnaehana ikehu: Ma ka hoʻohana ʻana i nā pale i hoʻokumu ʻia LZO i nā ʻāpana ʻenekini, hiki i nā ʻenekini mokulele a me nā turbine kinoea ke hana palekana i nā wela kiʻekiʻe. Ke alakaʻi nei kēia i ka hoʻopau ʻana i ka mana a me ka mana. I ka hoʻomaʻamaʻa ʻana, ua ʻike nā mea ʻenekinia ʻo TBC "mālama i ka mahana i loko o ke keʻena ʻā" a hoʻomaikaʻi i ka hana wela me ka hoʻemi ʻana i nā hoʻokuʻu. Ma nā huaʻōlelo ʻē aʻe, kōkua ka lanthanum zirconate coatings i ka mālama ʻana i ka wela ma kahi e pono ai (i loko o ke keʻena) a pale i ka nalowale ʻana o ka wela, no laila e hoʻohana pono nā ʻenekini i ka wahie. ʻO kēia synergy ma waena o ka insulation maikaʻi a me ka hoʻomaʻemaʻe hoʻomaʻemaʻe e kākoʻo ana i ka pilina o LZO i ka ikehu maʻemaʻe a me ka hoʻomau.
Eia kekahi, hoʻonui ka lōʻihi o LZO i nā wā mālama. ʻO kona kūpaʻa ʻana i ka sintering a me ka oxidation ʻo ia ka mea e paʻa mau ka papa ceramic ma o nā pōʻai wela. Hiki i kahi lanthanum zirconate TBC i hoʻolālā maikaʻi ʻia ke hoʻohaʻahaʻa i ka hoʻokuʻu ʻana o ke ola holoʻokoʻa ma o ka hoʻemi ʻana i nā wahi pani a me ka manawa haʻahaʻa. ʻO ka hōʻuluʻulu manaʻo, ʻo nā uhi LZO i hoʻoheheʻe ʻia i ka plasma he ʻenehana hoʻoikaika nui no ka hanauna e hiki mai ana i nā turbines kiʻekiʻe a me nā aero-engines.
Nā Hana Hana ʻē aʻe
Ma waho aʻe o nā TBC-sprayed plasma, loaʻa nā waiwai kūʻokoʻa o ka lanthanum zirconate i hoʻohana ʻia i nā seramika holomua.
● Heat and Sound Insulation: E like me ka mea i hōʻike ʻia e nā mea hana, hoʻohana ʻia ʻo LZO i nā mea insulating maʻamau. No ka laʻana, hiki i ka porous lanthanum zirconate ceramics ke ālai i ke kahe wela a me ka hoʻoheheʻe ʻana i ke kani. Hiki ke hoʻohana ʻia kēia mau panela insulating a i ʻole nā fibers i loko o nā linings umu a i ʻole nā mea kūkulu hale kahi e pono ai ka insulation kiʻekiʻe.
● Catalysis: ʻO ka Lanthanum oxides i ʻike ʻia he catalysts (e laʻa me ka hoʻomaʻemaʻe ʻana a i ʻole ka hoʻomalu ʻana i ka haumia), a hiki i ka hale o LZO ke hoʻokipa i nā mea catalytic. I ka hoʻomaʻamaʻa ʻana, hiki ke hoʻohana ʻia ʻo LZO ma ke ʻano he kākoʻo a i ʻole nā mea hoʻohui i nā catalysts no ka hopena o ke kinoea. ʻO kona kūpaʻa i ka wela kiʻekiʻe he mea hoihoi ia no nā kaʻina hana e like me ka hoʻololi ʻana i ka syngas a i ʻole ka hoʻomaʻamaʻa ʻana i nā kaʻa, ʻoiai ke kū nei nā hiʻohiʻona kikoʻī o La₂Zr₂O₇ i ka noiʻi.
● Mea Optical a me Fluorescent: ʻO ka mea hoihoi, hiki ke hoʻopaʻa ʻia ka lanthanum zirconate me nā iona honua laha ʻole e hana ai i nā phosphors a i ʻole scintillators. Hōʻike ʻia ka inoa o ka mea ma nā wehewehe o nā mea fluorescent. No ka laʻana, hiki i ka doping LZO me ka cerium a i ʻole europium ke hāʻawi i nā kristal luminescent kūʻokoʻa kiʻekiʻe no ka kukui a i ʻole nā ʻenehana hōʻike. Hiki i kona ikehu phonon haʻahaʻa (ma muli o nā paʻa oxide) hiki ke hoʻohana pono i nā optics infrared a i ʻole scintillation.
● Mea Kiʻekiʻe Kiʻekiʻe: Ma kekahi mau noi kūikawā, ua aʻo ʻia nā kiʻiʻoniʻoni lanthanum zirconate ma ke ʻano he haʻahaʻa-k (dielectric haʻahaʻa) insulators a i ʻole diffusion barriers i microelectronics. ʻO kona kūpaʻa ʻana i ka ea hoʻoneʻe ʻana a me nā voltages kiʻekiʻe (ma muli o ka bandgap kiʻekiʻe) hiki ke hāʻawi i nā pōmaikaʻi ma mua o nā oxides maʻamau i nā kaiapuni uila paʻakikī.
● ʻOki ʻoki a me nā ʻāpana ʻāpana: ʻOiai ʻaʻole maʻamau, ʻo ka paʻakikī o LZO a me ke kūpaʻa wela e hiki ke hoʻohana ʻia ma ke ʻano he pale pale paʻa i nā mea hana, e like me ke ʻano o ka hoʻohana ʻia ʻana o nā pale seramika ʻē aʻe no ke kūpaʻa ʻaʻahu.
ʻO ka versatility o La₂Zr₂O₇ kumu mai ia mea he seramika e hui pū ana i ka kemika o ka honua me ka paʻakikī o ka zirconia. He ʻāpana ia o ke ʻano ākea o nā seramika "rare-earth zirconate" (e like me ka gadolinium zirconate, ytterbium zirconate, a me nā mea ʻē aʻe) i hana ʻia no nā kūlana wela kiʻekiʻe.
Nā Pōmaikaʻi Kaiapuni a me ka Pono
Hāʻawi ka Lanthanum zirconate i ka hoʻomau ma mua o ka ikaika o ka ikehu a me ka lōʻihi. Ma ke ʻano he insulator thermal, hiki i nā mīkini ke hoʻokō i ka hana like me ka wahie liʻiliʻi. No ka laʻana, hiki i ka uhi ʻana i ka pahi turbine me LZO ke hōʻemi i ka leaka wela a pēlā e hoʻomaikaʻi ai i ka pono holoʻokoʻa o ka mīkini. ʻO ka hoʻemi ʻia ʻana o ka wahie e unuhi pololei i ka hoʻokuʻu ʻana o CO₂ a me NOₓ i kēlā me kēia ʻāpana o ka mana. I loko o kekahi noiʻi hou, ʻo ka hoʻohana ʻana i nā uhi LZO i loko o kahi ʻenekini hoʻopau i loko me ka biofuel i loaʻa i ka ʻoi aku ka maikaʻi o ka wela o ka brake a ʻoki loa i nā hoʻokuʻu kalapona monoxide. ʻO kēia mau hoʻomaikaʻi ʻo ia nā ʻano o ka loaʻa i ʻimi ʻia i ka holo ʻana i ka hoʻomaʻemaʻe hoʻomaʻemaʻe a me nā ʻōnaehana ikehu.
ʻO ka ceramic ponoʻī he chemically inert, ʻo ia hoʻi, ʻaʻole ia e hana i nā huahana ʻino. ʻAʻole e like me nā insulators organik, ʻaʻole ia e hoʻokuʻu i nā pūhui volatile i ka wela kiʻekiʻe. ʻO ka ʻoiaʻiʻo, ʻo kona kūpaʻa kiʻekiʻe-mehana a hiki ke kūpono i nā wahie e puka mai ana a me nā kaiapuni (e laʻa me ka puhi ʻana o ka hydrogen). ʻO nā loaʻa maikaʻi i hāʻawi ʻia e LZO i nā turbines a i ʻole nā mea hoʻomohala e hoʻonui i nā pono hoʻomau o nā wahie maʻemaʻe.
ʻO ka lōʻihi a me ka hoʻohaʻahaʻa ʻana i ka ʻōpala: ʻo ke kūʻē ʻana o LZO i ka hoʻohaʻahaʻa (sintering and oxidation resistance) ʻo ia hoʻi ka lōʻihi o ke ola no nā mea i uhi ʻia. Hiki ke hoʻohana lōʻihi ʻia ka lau turbine me ka LZO topcoat lōʻihi ma mua o ka mea i uhi ʻole ʻia, e hōʻemi ana i ka pono o nā pani a pēlā e mālama ai i nā lako a me ka ikehu i ka holo lōʻihi. He pōmaikaʻi kaiapuni kūʻokoʻa kēia paʻa, no ka mea, ʻoi aku ka liʻiliʻi o ka hana ʻana.
Eia nō naʻe, he mea nui e noʻonoʻo i ke ʻano o ka rare-earth element. He honua laha ka Lanthanum, a e like me ia mau mea a pau, ua hoʻonui ʻia nā nīnau hoʻomau. Inā ʻaʻole mālama pono ʻia, hiki ke hoʻopilikia i ke kaiapuni ka unuhi ʻana o ka honua. Ua ʻike ʻia nā loiloi hou i ka lanthanum zirconate coatings "loaʻa i nā mea ʻeleʻele ʻeleʻele, kahi e hāpai ai i ka hoʻomau a me nā pilikia ʻona e pili ana i ka ʻeli ʻana o ka honua a me ka hoʻokuʻu ʻana i nā mea". Hōʻike kēia i ka pono no ka loaʻa ʻana o ke kuleana o La₂Zr₂O₇ a me nā hoʻolālā hana hou ʻana no nā uhi i hoʻopau ʻia. Nui nā ʻoihana i ka ʻoihana waiwai holomua (me nā mea hoʻolako epomaterial) e noʻonoʻo i kēia a hoʻoikaika i ka maʻemaʻe a me ka hōʻemi ʻana i ka ʻōpala i ka hana.
Ma ka hōʻuluʻulu manaʻo, ʻoi aku ka maikaʻi o ka hopena o ke kaiapuni o ka hoʻohana ʻana i ka lanthanum zirconate i ka wā e ʻike ʻia ai nā pono kūpono a me ke ola. Ma ka ʻae ʻana i ka hoʻopau ʻana i ka hoʻomaʻemaʻe a me nā mea hana lōʻihi, hiki i nā seramika ma LZO ke kōkua i nā ʻoihana e hoʻokō i nā pahuhopu ikehu ʻōmaʻomaʻo. ʻO ka mālama pono ʻana i ka pōʻaiapuni o nā mea he mea nui e noʻonoʻo like ai.
Manaʻo a me nā loina e hiki mai ana
Ke nānā nei i mua, hoʻomaka ka lanthanum zirconate e ulu i ka mea nui i ka ulu ʻana o ka hana holomua a me ka ʻenehana maʻemaʻe.
● Nā Turbine Hana Hou:Ke koi nei nā mokulele a me nā turbine mana no nā mahana hana kiʻekiʻe (no ka maikaʻi a i ʻole ka hoʻololi ʻana i nā wahie ʻē aʻe), he mea koʻikoʻi nā mea TBC e like me LZO. Ke hoʻomau nei ka noiʻi ʻana i nā ʻaʻahu multi-layer kahi e noho ai kahi papa o ka lanthanum zirconate a i ʻole LZO doped ma luna o kahi papa YSZ kuʻuna, e hui pū ana i nā waiwai maikaʻi loa o kēlā me kēia.
● Aerospace a me ka pale kaua:ʻO ke kūʻē ʻana o ka radiation o ka mea (i ʻike ʻia ma kekahi mau haʻawina) hiki ke hoʻohiwahiwa i ka lewa a i ʻole nā noi pale nuklea. ʻO kona kūpaʻa ma lalo o ka irradiation particle kahi wahi o ka noiʻi ikaika.
● Mea hoʻololi ikehu:ʻOiai ʻaʻole he electrolyte maʻamau ʻo LZO, ʻimi kekahi mau noiʻi i nā mea pili i ka lanthanum i loko o nā pūnaeau wahie paʻa-oxide a me nā cell electrolysis. (ʻO ka manawa pinepine, hana ʻole ʻo La₂Zr₂O₇ ma ke kikowaena o nā electrodes lanthanum cobaltite a me YSZ electrolytes.) Hōʻike kēia i kona kūlike me nā kaiapuni electrochemical koʻikoʻi, hiki ke hoʻoulu i nā manaʻo hou no nā reactors thermochemical a i ʻole nā mea hoʻololi wela.
● Hoʻoponopono Mea Hana:Ke piʻi nei ka makemake o ka mākeke no nā seramika kūikawā. Hāʻawi nā mea hoʻolako i kēia manawa ʻaʻole wale i ka LZO maʻemaʻe kiʻekiʻe akā ʻo nā ʻano like ʻole ka ion-doped (no ka laʻana, hoʻohui i ka samarium, gadolinium, a me nā mea ʻē aʻe e hoʻololi i ka lattice kristal). Ua ʻōlelo ʻo EpoMaterial i ka hiki ke hana i ka "doping ion a me ka hoʻololi" o ka lanthanum zirconate. Hiki i ia doping ke hoʻoponopono i nā waiwai e like me ka hoʻonui ʻana i ka wela a i ʻole conductivity, e ʻae ana i nā ʻenekinia e hoʻoponopono i ka ceramic no nā kaohi ʻenehana kikoʻī.
● Nā loina honua:Me ka manaʻo nui o ka honua i ka hoʻomau a me ka ʻenehana holomua, nā mea e like me ka lanthanum zirconate e huki i ka nānā. ʻO kāna kuleana i ka hiki ʻana i nā ʻenekini kiʻekiʻe e pili i nā kūlana hoʻokele waiwai a me nā hoʻoponopono ikehu maʻemaʻe. Eia kekahi, hiki i ka hoʻomohala ʻana i ka paʻi 3D a me ka hana seramika ke maʻalahi i ka hana ʻana i nā ʻāpana LZO a i ʻole ka uhi ʻana i nā ala hou.
ʻO ka mea nui, hōʻike ka lanthanum zirconate i ke ʻano o ka hoʻokō ʻana i nā pono o ke kenekulia 21. ʻO kāna hui pū ʻana o ka versatility rare-earth a me ka paʻakikī ceramic e hoʻohālikelike iā ia me nā ʻano mea nui: ka mokulele hoʻomau, hana mana, a ma waho. Ke hoʻomau nei ka noiʻi (e ʻike i nā loiloi hou ma LZO-based TBCs), e puka mai ana nā noi hou, e hoʻopaʻa hou ana i kona koʻikoʻi i ka ʻāina ʻenehana holomua.
Lanthanum zirconate (La₂Zr₂O₇) he seramika hana kiʻekiʻe e hui pū ana i ka mea maikaʻi loa o ka lāʻau lāʻau oxide chemistry a me ka insulation thermal kiʻekiʻe. Me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, kiʻekiʻe-mehana paʻa, a me ka pyrochlore paʻa paʻa, ua kūpono loa ia no nā pale pale wela i hoʻoheheʻe ʻia i ka plasma a me nā noi insulation ʻē aʻe. Hiki i kāna hoʻohana ʻana i nā TBC aerospace a me nā ʻōnaehana ikehu ke hoʻomaikaʻi i ka maikaʻi a hōʻemi i ka hoʻokuʻu ʻana, e hāʻawi ana i nā pahuhopu hoʻomau. Hāʻawi nā mea hana e like me EpoMaterial i nā pauka LZO maʻemaʻe kiʻekiʻe no kēia mau noi ʻoki. Ke hoʻoikaika nei nā ʻoihana honua i ka ikehu maʻemaʻe a me nā mea akamai, kū ka lanthanum zirconate ma ke ʻano he seramika koʻikoʻi i ka ʻenehana - hiki ke kōkua i ka mālama ʻana i nā ʻenekini, ʻoi aku ka ikaika, a me nā ʻōnaehana ʻōmaʻomaʻo.
