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 ʻano honua laha 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 nā mea mālama hydrogen, thermoelectric mea, cerium tungsten electrodes, ceramic capacitors, piezoelectric ceramics, cerium. ʻO nā mea abrasive silicon carbide, nā mea hoʻoheheʻe wahie, nā mea magnet mau loa, nā uhi, nā mea hoʻonaninani, nā mea hao, nā mea hao like ʻole, nā laser a me 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 ua hoʻohana ʻia ka cerium ammonium nitrate 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.
