Kipuka ʻO ke kaikunāne nui o ka 'o ke aloha' i loko o kaʻohana nui o nā mea he nui o nā'āina. ʻO ka mua, ka nui o ka nui o nā'ōiwi o nāʻanuʻu ma ka crust he 238ppm, me ka cerium, me ka nui o ka nui o ka honua ʻO ka lua,ʻo Cerum ka lua o ka Honua e loaʻa i nā makahiki heʻeiwa ma hope o ka loaʻaʻana o ka nui o ka yttrium (1794). He nui loa kāna noi, a me "cerum"ʻaʻole i hiki
ʻO ka loaʻaʻana o ka Cerums
Carl Auer von Welsbach
Uaʻikeʻiaʻo Cerium a i kapaʻia ma 1803 e nā Kloppers Kelemania, Sweden Ghim Ua kapaʻiaʻo iaʻo Misa, aʻo ia ka mea i kapaʻiaʻo ke kamelo, i ke hoʻomanaʻoʻana i nā kīʻaha, he meaʻulaʻula, kahi o nā mea kūʻai, kahi mea kūʻai, ayttrium.
ʻO ka hoʻohana muaʻana o Cerium ka mea i hoʻopaʻaʻia e ka pahu ahi ahi e hanaʻia e Austrian chemist carl Averbach. I ka makahiki 1885, ua ho'āʻoʻo ia i ka huiʻana o ka Magnie, Lanthanum, a me Yttrium Oxide, akāʻo kēia mauʻano hoʻohālikelike i kahi kukui'ōmaʻomaʻo.
I ka makahiki 1891, ua loaʻa iā ia ua hanaʻiaʻo kicela maʻemaʻe i ke kukui,ʻoiai he polū ia e hana i kahi kukui keʻokeʻo. Ma kahi o ka cerium (iv) hiki ke hoʻohanaʻia e like me ka catalyst no ka thorium mixide
Cerium Metal
★ Ceruum kahi mea kīwī keʻokeʻo a me nā mea kīwī gula maikaʻi me nā waiwai ikaika. Keʻikeʻia i ka lewa, e hoʻopiliʻia, e hana ana i kahi pū me ka hoʻowalewaleʻana i ke kaha makiʻana. I ka wā e hoʻomehana ai, e wela ana a hoʻohuli i ka wai me ka wai. ʻO kahi centimeter ka cerium cerium cerium circle circle i loko o ka makahiki i loko o kahi makahiki. Hōʻalo i ka hoʻopiliʻana me ka ea, nā pelika ikaika, nā maʻi ikaika, ikaika.
★ Cerum nui nui ma Monazite a me Basnaesite, a me nā huahana o nā huahana Urani nui, a me nā pumituim. Hanaʻino i ke kaiāulu, pono e ukuʻia ka nānā ponoʻana i ka hōʻeha o nā kino wai.
★ Cerum ka 26 o ka nui loa e pili ana i ka nui, accounting no 68ppm o ka lepo o ka honua,ʻelua wale nō copper (68ppm). ʻOi aku ka nui o ka Cerium ma mua o nā metals maʻamau e like me ke alakaʻi (13PM) a me TIN (2.1PPM).
Cerium Electron Contuffuration
Nā hoʻonohonoho uila:
1s2 2s2 4002 3s22 3006 4D10 4P6 6DS6S2 4D10 5D1
★ʻO Cerumum ma hope o Lanthanum a loaʻa iā 4f Electrons e hoʻomaka ana mai Cerium, e maʻalahi ke komo i nā hopena Chemical. Eia nō naʻe,ʻo ka 5d orbital o Cerium ka nohoʻia,ʻaʻole ikaika i kēia hopena i ka cerium.
★ʻO ka hapanui o ka Lanthannide ke hoʻohana wale i nā koho balotaʻekolu e like me Valence Electron, me kaʻokoʻa o ka Cerum,ʻo ia kahiʻano uila uila. ʻO ka ikaika o nā electrons 4f ma kahi o nā mea likeʻole o ka ma waho o kēia mau mea hoʻohana, aʻo kahi liʻiliʻi wale nō e pono ai e hoʻololi i ka nui o nā papa hana uila o + 3 a me + + 4. ʻO ka moku'āina maʻamau he + 3 Valence, e hōʻike ana + 4 Velence ma ka wai anaerobic wai.
Noi noi cerium
★ Hiki ke hoʻohanaʻia e like me keʻano alloy addy a no ka hanaʻana o nā cerium paʻakai, etc.
★ Hiki iā ia ke hoʻohanaʻia e like me ke aniani e hoʻohui ai i ka hoʻohui ultrabollet a infrared geys, a hoʻohana nuiʻia i ke aniani kaʻa.
★ Hiki ke hoʻohanaʻia e like me kahi mea palekana palekana o ka honua,ʻo ia ka meaʻoi loa ka mea iʻikeʻia i kahi kaʻa kaʻa kaʻa kaʻa i ka lewa i ka lewa.
HoʻopihiNā Kūlana HonuaʻO ka mea nui i hoʻokumuʻia e ka cerium e like me nā mea kanu ulu ulu e hoʻomaikaʻi i ka maikaʻi o ka chop
★ Cerum Sulfide hiki ke hoʻololi i nā metala e like me ke alakaʻi a me ka cadmium e pōʻino ana i nā kiʻi a me keʻano o nā mea kanu.
Hana '★Cerium (IV)hiki ke hoʻohanaʻia e like me ka hoʻohuiʻana i ka poli, no ka laʻana, i loko o ka pohō o ka lāʻau lapaʻau (cmp).
★ Cerum ke hoʻohana pūʻia e like me nā mea mālama hydrogen, nā mea kūʻai aku, nā mea lapaʻau cerily.
