Ke wehe nei i ke kumu o ka Scandium Oxide

Hōʻike ʻia ka ʻike kino o ka scandium oxide e kona ʻano ikaika o ka wela, e hōʻike ana i kahi helu hoʻoheheʻe kiʻekiʻe loa e hāʻule maʻamau i loko o ka laulā o 2400 a 2485 degere Celsius, he hōʻike i nā pūʻali interatomic ikaika i loko o kāna lattice crystalline. ʻOi aku ka kiʻekiʻe o kona wahi paila, e hōʻike hou ana i kona ʻano refractory a me kona hiki ke kū i nā kaiapuni wela loa me ka ʻole o ka hoʻololi ʻana i ka pae deleterious. Me ka umekaumaha kiko'ī ma kahi o 3.86 grams no ka cubic centimeter, loaʻa iā ia ka haʻahaʻa haʻahaʻa, kahi mea e hoʻohuli ai i ka noʻonoʻo paona holoʻokoʻa i nā noi kahi mea hoʻolālā koʻikoʻi ka māmā. Eia kekahi, hōʻike ʻia ka scandium oxide i ka insolubility i loko o ka media aqueous, kahi ʻano i loaʻa mai ka paʻa ʻana o ka ionic i loko o kona hale, ʻoiai e hoʻopau koke ʻia i loko o nā ʻakika mineral concentrated ma ka hoʻomehana ʻana, e hana ana i nā paʻakai scandium pili, kahi ʻano kemika i hoʻohana ʻia i nā ʻano hana synthetic a me ka hoʻomaʻemaʻe. Me kemika,scandium oxidehōʻike i nā manaʻo amphoteric, ʻoiai ua ʻoi aku kona ʻano kumu ma mua o kona ʻakika, e ʻae iā ia e hana me nā ʻano acidic e hana i nā paʻakai. ʻO ka mea e mahalo ai, hiki iā ia ke komo i ke kalapona kalapona o ka lewa, ʻoiai ke alo o ka makū, e alakaʻi ana i ka hoʻokumu ʻana o nā carbonates surface a i ʻole hydroxycarbonates, kahi mea e pono ai ka mālama pono ʻana e mālama i kona maʻemaʻe.

Ma waho aʻe o kona mau hiʻohiʻona ʻike, hōʻike ʻia ka scandium oxide i kahi ʻano hoihoi o nā waiwai optical a me nā uila e hoʻohana nui ʻia nei i nā ʻenehana holomua. ʻO kāna helu helu refractive, kiʻekiʻe ma kahi o 1.85 a 1.96 e pili ana i ka lōʻihi o ka nalu a me ka nui o nā mea waiwai, he mea waiwai ia i ka hana ʻana i nā uhi a me nā lens, e hoʻonui ai i ka pono o ka lawe māmā a me ka manipulation. Ke hōʻike nei i ka transmissivity koʻikoʻi ma waena o nā ʻāpana ʻike a kokoke i ka infrared o ka spectrum electromagnetic, lawelawe ia ma ke ʻano he mea koʻikoʻi i nā puka aniani a ma ke ʻano he substrate māmā no nā kiʻiʻoniʻoni ʻoniʻoni i nā mea optoelectronic. Eia kekahi, i ka wā i hoʻopaʻa ʻia me nā ion honua laha ʻole, hōʻike ka scandium oxide i ka photoluminescence, e hoʻokuʻu ana i ka mālamalama o nā lōʻihi hawewe kikoʻī ma luna o ka hauʻoli, kahi waiwai i waena o kāna hoʻohana ʻana i nā kukui kūpaʻa ikaika a me nā ʻenehana hōʻike kiʻekiʻe. I kona kūlana koʻikoʻi, hana ʻo scandium oxide ma ke ʻano he insulator uila, ʻike ʻia e ka resistivity kiʻekiʻe, kahi ʻano koʻikoʻi no kāna noi ʻana ma ke ʻano he mea dielectric i nā mea uila, e pale ana i ka leakage makemake ʻole. ʻO kāna mau dielectric kiʻekiʻe e hoʻolilo iā ia i kūpono no ka hoʻohana ʻana i nā capacitors, e hoʻomaʻamaʻa i ka mālama ʻana i ka ikehu i loko o nā kaapuni uila.

No ka hoʻomaopopo ʻana i ke ʻano macroscopic o ka scandium oxide, ʻo ka hoʻomaopopo ʻana i kāna ʻano hana atomic lalo ka mea nui. He crystallize ia i loko o ka cubic Bixbyite structure, he kumu maʻamau i waena o ka honua sesquioxides, i hōʻike ʻia e ka hoʻonohonoho cubic alo o nā anion oxide me nā scandium cations e noho ana i nā wahi octahedral kikoʻī, ʻoiai me nā hakahaka anionic inherent. ʻO kēia mau hiʻohiʻona hoʻolālā e kuhikuhi i nā mamao interatomic a me nā kihi hoʻopaʻa, i ka hopena i ka hopena o ka paʻa a me nā waiwai. ʻO ka hoʻopaʻa ʻana a me ka paʻa o ka ionic hoʻopaʻa ʻana i loko o kēia lattice kristal e hāʻawi nui i ka helu heheʻe kiʻekiʻe o ka mea a me ka inertness kemika ma lalo o nā kūlana he nui.

Ma waho aʻe o kāna mau hiʻohiʻona kumu, hōʻike ʻia ka scandium oxide i kahi ʻano o nā waiwai holomua a me nā mea e ulu nei e ʻimi nei i ka hoihoi nui i ka noiʻi ʻokiʻoki. Hōʻike kona ʻili i ka hana catalytic no kekahi mau hoʻololi kemika, a ke ʻimi ʻia nei kona hiki ke adsorb i nā molekala like ʻole i nā ʻenehana sensor. ʻOiai he insulator uila, loaʻa iā ia kahi conductivity thermal i hiki ke ana i ka wela, kahi mea koʻikoʻi i nā noi uila mana kiʻekiʻe. ʻO kona ʻano haʻahaʻa haʻahaʻa o ka hoʻonui ʻana i ka wela e hōʻoia i ka paʻa ʻana o ka dimensional ma waena o nā ʻano wela, kahi ʻano makemake i ka ʻenekinia pololei. Eia kekahi, ʻo kona paʻakikī koʻikoʻi a me ka paʻakikī haʻihaʻi haʻahaʻa e kōkua i kona kūpaʻa i ke koi ʻana i nā kaiapuni mechanical.

ʻO ka mea hope loa, ʻo ka hui pū ʻana o ka scandium oxide o ke kino, kemika, optical, electronic, a me nā waiwai mechanical e kuhikuhi i kāna ʻano like ʻole a me ka hoʻonui ʻana o nā noi. ʻO kona kūpaʻa wela a me nā waiwai luminescent e kākoʻo i kāna hoʻohana ʻana i nā kukui kiʻekiʻe. ʻO kona hiki ke hoʻonui i ka ikaika a me ka weldability o nā alumini alumini, ma o ka hoʻomaʻemaʻe ʻana i ka palaoa, he mea koʻikoʻi i ka aerospace a me ka ʻenehana automotive. Hoʻohana ʻia kāna mau dielectric a me ka insulating i nā seramika uila a me nā capacitors. Hoʻohana ʻia kāna ʻōlelo kuhikuhi refractive a me ke aniani i nā uhi optical. ʻIke ʻia ka hana catalytic o kona ʻili i ka synthesis kemika, a hoʻohana ʻia kona hiki adsorption i nā ʻenehana sensor. ʻO ka doping i hoʻohālikelike ʻia o ka scandium oxide me nā mea ʻenehana honua hiki ke hana i nā phosphors kūikawā no nā kukui kiʻekiʻe a me nā noi hōʻike. Ke hoʻomau nei ka noiʻi e wehe i nā mea paʻakikī o kāna mau waiwai a e ʻimi i nā ʻano hana synthesis novel, ua mākaukau nā noi o ka scandium oxide no ka hoʻonui hou ʻana, e hoʻoikaika ana i kāna kuleana ma ke ʻano he mea koʻikoʻi i ka holomua ʻenehana e hiki mai ana.
