Cerium oxide ni iki?

Cerium oxide nigikoresho kidasanzwe hamwe na chacelatula ya chimique umuyobozi mukuru, ifu yumuhondo cyangwa umuhondo yijimye yijimye. Ubucucike 7.13g / CM3, Gushonga Ingingo ya 2397 ° C, ihungabanye mumazi na alkali, gushonga gato muri aside. Ku bushyuhe bwa 2000 ° C hamwe nigitutu cya 15mpa, hydrogen birashobora gukoreshwa mukugabanya oriude oxide kugirango ubone cerium oxide. Iyo ubushyuhe butarimo 2000 ° C kandi igitutu ni ubuntu kuri 5mpa, orium oxide ni umutuku wumuhondo umutuku, nijimye. Ikoreshwa nkibintu byoroshye, umusemburo, umutwara neza (abafasha), ultraviolet assorber, laweli selile ya electrolyte, guhumeka kwa electrous, gukomera kwimodoka, nibindi.
Amakuru yumutekano
Umunyu waceride oxideIbintu bidasanzwe byisi birashobora kugabanya ibikubiye muri Prothromin, bidakora, bibuza igisekuru cya Throminage, mvuza fibrinogen, na Catalinee depposition of acide ya fosifori. Uburozi bwibintu bidasanzwe byisi bigabanya uburemere bwa atomic.
Guhumeka umukungugu wa Cerium urashobora gutera proumoconiose yakazi, kandi chloride yayo irashobora kwangiza uruhu no kurakaza intoki za mucous mumaso.
Igitabo ntarengwa cyemewe: Cerium oxide 5 mg / m3, cerium hydroxide 5 mg / m3, uburinzi budasanzwe bugomba gukorwa, kandi umukungugu ugomba gukumirwa, kandi umukungugu ugomba gukumirwa no gutatanya.
kamere
Ibicuruzwa byera ni ifu ndende yera cyangwa cubic Crystal, kandi ibicuruzwa byanduye ni umuhondo wumuhondo cyangwa umutuku kugirango ucike intege (kuko ikubiyemo ibimenyetso bya LANEDANIM (kuko ikubiyemo ibimenyetso bya Lanthanam, Praseoodymium, nibindi). Hafi ihuriweho mumazi na aside. Ubucucike ugereranije 7.3. Gushonga Ingingo: 1950 ° C, ingingo itetse: 3500 ° C. Uburozi, igipimo cya Median cyica (imbeba, umunwa) ni hafi 1G / kg.
ububiko
Komeza umushyitsi.
Indangagaciro nziza
Igabanijweho isuku: Isuku yo hasi: Isuku itarenze 99%, isuku: 99.99% ~ 99.99%, Ultra-Usukuye Hejuru 99.999%
Kugabanwa nubunini bwanditse: ifu ya Coarse, Micron, Submirmiron, Nano
Amabwiriza yumutekano: Ibicuruzwa ni uburozi, butagereranywa, bidahwitse, umutekano kandi wizewe, uhagaze mubikorwa, kandi ntibitwara n'amazi nibinyabuzima. Ni ikirahuri cyiza-cyiza gishimangira umukozi, cyera umukozi numukozi ufasha imiti.

okiside. Umusemburo kubitekerezo kama. Isesengura ryicyuma nicyuma nkibice bidasanzwe byimbuto zisanzwe. Isesengura ry'igice cya Redox. Ikirahure cya decolorinded. Vitreous enamel opacifier. Ubushyuhe burwanya ubushyuhe.
Byakoreshejwe nkinyongera mubirahure, nkibikoresho byo gusya kubirahuri, kandi nkingaruka zo kurwanya ultraviole muri kwisiga. Yaguwe kugeza gusya ikirahuri cyimbitse, lens optique, no gushushanya umuyoboro wo gutesha agaciro, no gusobanura, no kwinjiza imirasire ya ultraviolet hamwe nimirasire yikirahure.
