Ko te Cerium oxide he matū pararopi me te tauira matū CeO2, he kowhai marama, he kowhai parauri ranei he paura awhina.Kiato 7.13g/cm3, ira whakarewa 2397°C, karekau e rewa i roto i te wai me te kawakore, paku wairewa ki te waikawa.I te mahana o te 2000°C me te pehanga o te 15MPa, ka taea te whakamahi hauwai hei whakaiti i te waikura cerium kia whiwhi ai i te waikura cerium.I te wa e waatea ana te mahana i te 2000°C me te kore utu o te pehanga i te 5MPa, he paku kowhai whero te waikura cerium, he mawhero hoki.Ka whakamahia hei mea whakakorikori, he whakakorikori, he kawe whakakorikori (awhinahina), he tango i te ultraviolet, he hiko hiko wahie, he whakangao ngongo motuka, he hiko hiko, aha atu.
Mōhiohio Haumarutanga
Te tote ocerium waikuraKa taea e nga huānga whenua onge te whakaiti i te ihirangi o te prothrombin, te whakakore i te mahi, te aukati i te whakatipuranga o te thrombin, te whakaheke i te fibrinogen, me te whakakorikori i te pirau o nga pūhui waikawa phosphoric.Ka ngoikore te paitini o nga mea onge whenua na te pikinga o te taumaha ngota.
Ko te whakaurunga o te puehu cerium ka puta te pneumoconiosis mahi, ka taea e tana chloride te kino te kiri me te whakapouri i nga kiriuhi mucous o nga kanohi.
Ko te nui o te kukū e whakaaetia ana: cerium oxide 5 mg/m3, cerium hydroxide 5 mg/m3, me mau nga kopare hau i te wa e mahi ana, me tiaki motuhake mena he radioactivity, me aukati te puehu kia kore e marara.
taiao
Ko te hua parakore he paura taumaha ma, he karaihe putorino ranei, ko te hua poke he kowhai marama, he mawhero ranei ki te parauri whero (na te mea kei roto nga tohu o te lanthanum, praseodymium, me etahi atu).Tata korekore ki te wai me te waikawa.Kiato whanaunga 7.3.Ira whakarewa: 1950°C, ira koropuke: 3500°C.He paitini, ko te horopeta whakamate (kiore, waha) tata ki te 1g/kg.
toa
Kia mau te hau.
Taurangi Kounga
Wehehia e te ma: iti te parakore: te parakore e kore e teitei ake i te 99%, te parakore teitei: 99.9% ~ 99.99%, te maamaa teitei i runga ake i te 99.999%
Kua wehea e te rahi matūriki: te paura parakore, te micron, te submicron, te nano
Nga tohutohu haumaru: Ko te hua he paihana, he kore reka, he kore-riri, he haumaru me te pono, he pumau te mahi, kaore hoki e tauhohe ki te wai me te mea pararopi.He kaihoko whakamaarama karaehe kounga teitei, he kaihoko whakaheke tae me te kaihoko awhina matū.
whakamahi
kaiwhakawai hāora.He whakakōkī mō ngā tauhohenga waro.Te wetewete rino me te rino hei tauira paerewa whakarewa whenua onge.Te tātari titration Redox.Karaehe kua whakakorehia te tae.Vitreous enamel opacifier.koranu whakawera wera.
Ka whakamahia hei taapiri i roto i te ahumahi karaihe, hei taputapu huri mo te karaihe pereti, me te mahi anti-ultraviolet i roto i nga mea whakapaipai.Kua whakawhänuihia ki te hurihanga o te karaehe tirohanga, te arotahi whatu, me te ngongo pikitia, me te mahi i nga mahi o te whakaheke, te whakamarama, me te whakauru o nga hihi ultraviolet me nga hihi hiko o te karaihe.
