Niki Cerium Oxide？

Cerium oxyde ni ibintu bidasanzwe hamwe na formula ya chimique CeO2, ifu yumuhondo yijimye cyangwa umuhondo wijimye. Ubucucike 7.13g / cm3, gushonga 2397 ° C, kudashonga mumazi na alkali, gushonga gato muri aside. Ku bushyuhe bwa 2000 ° C hamwe n’umuvuduko wa 15MPa, hydrogène irashobora gukoreshwa mu kugabanya okiside ya cerium kugirango ibone okiside ya cerium. Iyo ubushyuhe ari ubuntu kuri 2000 ° C naho umuvuduko ukaba kuri 5MPa, okiside ya cerium iba umutuku wijimye wijimye, kandi wijimye. Ikoreshwa nkibikoresho byo gusya, catalizator, itwara catalizator (auxiliary), imashini ya ultraviolet, moteri ya lisansi electrolyte, imashini isohora ibinyabiziga, ibikoresho bya elegitoroniki, nibindi.
Amakuru yumutekano
Umunyu wacerium oxydeibintu bidasanzwe byubutaka birashobora kugabanya ibirimo prothrombine, ntibigire icyo bikora, bikabuza kubyara trombine, bigabanya fibrinogen, kandi bigatera kwangirika kwa acide fosifori. Uburozi bwibintu bidasanzwe byisi bigabanuka hamwe no kwiyongera kwuburemere bwa atome.
Guhumeka umukungugu urimo cerium birashobora gutera pneumoconiose yumurimo, kandi chloride yayo irashobora kwangiza uruhu no kurakaza ururenda rwamaso.
Ikigereranyo ntarengwa cyemewe: cerium oxyde 5 mg / m3, cerium hydroxide 5 mg / m3, masike ya gaze igomba kwambarwa mugihe ikora, hagomba gukorwa uburinzi bwihariye niba hari radio, kandi umukungugu ugomba kubuzwa gutatana.
kamere
Igicuruzwa cyera ni ifu yera iremereye cyangwa cristal cubic, kandi ibicuruzwa byanduye ni umuhondo wijimye cyangwa se umutuku wijimye wijimye (kuko urimo ibimenyetso bya lanthanum, praseodymium, nibindi). Hafi yo kudashonga mumazi na aside. Ubucucike bugereranijwe 7.3. Ingingo yo gushonga: 1950 ° C, ingingo itetse: 3500 ° C. Uburozi, ikigereranyo cyica hagati (imbeba, umunwa) ni 1g / kg.
ububiko
Komeza guhumeka neza.
Ironderero ryiza
Igabanijwe nubuziranenge: ubuziranenge buke: ubuziranenge ntiburenze 99%, ubuziranenge bwinshi: 99,9% ~ 99,99%, ubuziranenge bukabije hejuru ya 99,999%
Igabanijwe nubunini buke: ifu yuzuye, micron, submicron, nano
Amabwiriza yumutekano: Igicuruzwa ni uburozi, kitaryoshye, kidatera uburakari, umutekano kandi wizewe, gihamye mumikorere, kandi ntigikora hamwe namazi nibintu kama. Nibirahuri byujuje ubuziranenge bisobanura, ibikoresho bya decolorizing hamwe nubufasha bwimiti.
Koresha
okiside. Umusemburo wibisubizo kama. Isesengura ryibyuma nicyuma nkibisanzwe bidasanzwe byicyitegererezo. Isesengura rya titre ya Redox. Ikirahuri cyiza. Vitreous enamel opacifier. ibishishwa birwanya ubushyuhe.
Ikoreshwa nk'inyongera mu nganda y'ibirahure, nk'ibikoresho byo gusya ibirahuri by'isahani, kandi nk'ingaruka yo kurwanya ultraviolet mu kwisiga. Yaguwe no gusya ibirahuri by'indorerwamo, lens optique, hamwe na tube y'amashusho, kandi bigira uruhare mu gushushanya, gusobanura, no kwinjiza imirasire ya ultraviolet n'imirasire ya elegitoronike y'ikirahure.
