ʻO Cerium, ka inoa mai ka inoa Pelekane o ka asteroid Ceres. ʻO ka maʻiʻo o ka cerium i loko o ka ʻāʻī o ka honua ma kahi o 0.0046%, ʻo ia ka mea nui loa i waena o nā mea ʻano honua. Aia ka Cerium ma ka monazite a me ka bastnaesite, akā i loko o nā huahana fission o ka uranium, thorium, a me ka plutonium. ʻO ia kekahi o nā wahi kikoʻī noiʻi ma ka ʻepekema a me ka ʻepekema waiwai.
Wahi a ka ʻike i loaʻa, ʻaʻole hiki ke hoʻokaʻawale ʻia ka cerium ma kahi kokoke i nā kahua noi honua. Hiki ke wehewehe ʻia ʻo ia ka "waiwai a me ka nani" o nā mea o ka honua a me ka "kauka cerium" holoʻokoʻa i ka noi.
Hiki ke hoʻohana pololei ʻia ka Cerium oxide e like me ka pauka polishing, wahie additive, gasoline catalyst, exhaust gas purifier promoter, etc. Hiki ke hoʻohana ʻia ma ke ʻano he ʻāpana i loko o nā mea mālama hydrogen, thermoelectric mea, cerium tungsten electrodes, ceramic capacitors, piezoelectric ceramics, cerium silicon carbide abrasives, wahie cell maka, nā mea kila kila, nā mea kila kila a me nā mea hao. Nā metala non-ferrous, etc.
I nā makahiki i hala iho nei, ua hoʻohana ʻia nā huahana cerium oxide maʻemaʻe kiʻekiʻe i ka uhi ʻana o nā chips a me ka polishing o nā wafers, nā mea semiconductor, etc.; hoʻohana ʻia ka cerium oxide kiʻekiʻe i loko o nā kiʻi ʻoniʻoni ʻoniʻoni hou (LFT-LED) mea hoʻohui, polishing agents, a me nā corrosive kaapuni; Hoʻohana ʻia ka Cerium carbonate maʻemaʻe kiʻekiʻe no ka hana ʻana i ka pauka polishing maʻemaʻe kiʻekiʻe no nā kaʻa polishing, a hoʻohana ʻia ka cerium ammonium nitrate maʻemaʻe kiʻekiʻe ma ke ʻano he corrosive agent no nā papa kaapuni a me ka sterilization a me ka preservative no nā mea inu.
Hiki i ka Cerium sulfide ke pani i ke kēpau, cadmium a me nā metala ʻē aʻe e pōʻino i ke kaiapuni a me ke kanaka a hoʻohana ʻia i loko o nā puaʻa. Hiki iā ia ke kala i nā plastic a hiki ke hoʻohana ʻia i ka pena, ka inika, a me nā ʻoihana pepa.
ʻO ka ʻōnaehana laser Ce:LiSAF he laser solid-state i hoʻomohala ʻia e ʻAmelika Hui Pū ʻIa. Hiki ke hoʻohana ʻia e ʻike i nā mea kaua ola ma ka nānā ʻana i ka neʻe ʻana o tryptophan, a hiki ke hoʻohana ʻia i ka lāʻau lapaʻau.
He ʻokoʻa ka hoʻohana ʻana o ka cerium i ke aniani.
Hoʻohui ʻia ka Cerium oxide i ke aniani o kēlā me kēia lā, e like me ke aniani hoʻolālā a me ke aniani kaʻa, ke aniani aniani, hiki ke hōʻemi i ka lawe ʻana o nā kukuna ultraviolet, a ua hoʻohana nui ʻia ma Iapana a me ʻAmelika Hui Pū ʻIa.
Hoʻohana ʻia ka Cerium oxide a me ka neodymium oxide no ka decolorization aniani, e hoʻololi ana i ke keʻokeʻo keʻokeʻo decolorizing agent, ʻaʻole ia e hoʻomaikaʻi wale i ka pono, akā pale pū nō hoʻi i ka haumia o ka arsenic keʻokeʻo.
ʻO Cerium oxide kekahi mea hoʻonani aniani maikaʻi loa. Ke komo ke aniani alohilohi me ka mea kala ʻole honua i ke kukui ʻike ʻia me ka lōʻihi hawewe o 400 a 700 nanometers, hōʻike ia i kahi waihoʻoluʻu nani. Hiki ke hoʻohana ʻia kēia mau aniani kala e hana i nā kukui hoʻokele no ka mokulele, ka hoʻokele, nā kaʻa like ʻole, a me nā mea hoʻonaninani kiʻekiʻe. ʻO ka hui pū ʻana o ka cerium oxide a me ka titanium dioxide hiki ke hana i ke aniani melemele.
Hoʻololi ka Cerium oxide i ka arsenic oxide kuʻuna ma ke ʻano he mea hoʻoheheʻe aniani, hiki ke hoʻoneʻe i nā ʻōhū a me nā mea kala. He hopena koʻikoʻi ia i ka hoʻomākaukau ʻana i nā hue aniani kala ʻole. ʻO ka huahana i hoʻopauʻia he keʻokeʻo keʻokeʻo, maikaʻi keʻokeʻo, hoʻonui i ka ikaika aniani a me ka pale wela, a ma ka manawa like e hoʻopau i ka pollution o arsenic i ke kaiapuni a me ke aniani.
Eia kekahi, he 30-60 mau minuke e hoʻolalelale i ka lens me ka cerium oxide polishing pauka i hoʻokahi minuke. Inā hoʻohana ʻoe i ka pauka polishing iron oxide, 30-60 mau minuke. Loaʻa i ka Cerium oxide polishing powder nā mea maikaʻi o ka liʻiliʻi liʻiliʻi, ka wikiwiki polishing wikiwiki a me ka maikaʻi polishing kiʻekiʻe, a hiki ke hoʻololi i ka maikaʻi polishing a me ka hana ʻana. Hoʻohana nui ʻia ia i ka polishing o nā kāmela, nā lens kamera, nā kiʻi kiʻi TV, nā lens nānā, etc.
