ʻO ka mea Cerium (Ce)

Ua ʻike ʻia ka mea "cerium" a kapa ʻia i ka makahiki 1803 e ka mea ʻepekema Kelemania ʻo Martin Heinrich Klaproth a me nā mea kemika Suedena ʻo Jöns Jakob Berzelius a me Wilhelm Hisinger, no ka hanohano o ka asteroid Ceres, i ʻike ʻia ma 1801.

Loaʻa i ka Cerium kahi ākea o nā noi:
(1) Me he mea hoʻohui i ke aniani,ceriumHiki iā ia ke komo i ka radiation ultraviolet a me ka infrared radiation, e hoʻohana nui ʻia i ke aniani kaʻa. ʻAʻole pale wale kēia i nā kukuna ultraviolet akā e hoʻemi ana i ka mahana o loko o nā kaʻa, a laila e mālama ai i ka ikehu i hoʻohana ʻia no ka ea ea. Mai ka makahiki 1997, ua hoʻokomo ʻia nā aniani kaʻa a pau ma Iapana i ka cerium oxide, a i ka makahiki 1996, ua ʻai ʻo ʻAmelika ma luna o 1,000 tonscerium oxideno ke aniani kaʻa.

(2)Ceriumke hoʻohana ʻia nei i nā mea hoʻomaʻemaʻe hoʻomaʻemaʻe automotive, me ka pale ʻana i nā hoʻokuʻu nui ʻana o nā kinoea hoʻopau automotive i ka lewa. Ma ʻAmelika Hui Pū ʻIa, ʻo ka ʻai ʻana i ka cerium no kēia kumu he hapakolu o ka nui o ka hoʻohana ʻana i ka honua.

(3) Hiki i ka Cerium sulfide ke pani i nā metala pōʻino e like me ke kēpau a me ka cadmium i loko o nā puaʻa, kūpono no ka waihoʻoluʻu plastic, a me ka pena, ka inika, a me nā ʻoihana pepa.

(4) ʻO ka Ce: LiSAF laser system, kahi laser solid-state i hoʻomohala ʻia ma ʻAmelika Hui Pū ʻIa, hiki ke nānā i nā manaʻo tryptophan e ʻike i nā mea kaua ola a loaʻa nā noi lapaʻau.

ʻIke ʻia ka versatility o ka cerium ma nā ʻano he nui, me ka pauka polishing, nā mea mālama hydrogen, nā mea thermoelectric, cerium tungsten electrodes, ceramic capacitors, piezoelectric ceramics, cerium silicon carbide abrasives, fuel cell materials, gasoline catalysts, specific permanent permanent materials, alloys like ʻole. nā kila, a me nā metala kala.
