Yini i-centium oxide?

I-Cerium Oxide iyinto engafani ne-deo yefomula yamakhemikhali, ukukhanya okuphuzi noma okuphuzi okuphuzi onsundu. I-Density 7.13G / CM3, I-Seling Point 2397 ° C, inserfoble emanzini kanye alkali, incane kancane in acid. Emazingeni okushisa angama-2000 ° C kanye nengcindezi ye-15mpa, i-hydrogen ingasetshenziswa ukunciphisa i-cerceium oxide ukuthola i-certium oxide ukuthola i-certium oxide. Lapho izinga lokushisa likhululekile ku-2000 ° C kanti ingcindezi imahhala e-5MPA, i-certium oxide ibomvu kancane kancane, futhi ipinki. Isetshenziswa njengezinto ezibonakalayo zokuphamba, i-catalyst, i-carlyst carrier (auxilier), i-ultraviolet absorber, ama-free cell electrorberte, i-ceramics ye-accobobile, njll.
Imininingwane Yezokuphepha
Usawoti weI-Cerrium OxideIzinto zomhlaba ezingandile zinganciphisa okuqukethwe kwe-prothrombin, kungasebenzi, zivimbele isizukulwane se-thrombin, i-fibrinogen, futhi i-cataryche ukubola kwamakhompiyutha e-phosphoric acid. Ubuthi bezakhi zomhlaba ezingandile buble ukwenyuka kwesisindo se-athomu.
Ukuphefumula kothuli oluqukethe i-cersium kungadala i-pneumoniosis yomsebenzi, futhi i-chloride yayo ingalimaza isikhumba futhi icasule ulwelwesi lwama-mucous amehlo.
Ukuhlushwa okuvunyelwe okuvunyelwe okuphezulu
uhlobo
Umkhiqizo omsulwa yi-White Heave powder noma i-cubic crystal, futhi umkhiqizo ongcolile uphuzi ophuzi noma upinki ukuze ubomvu onsundu (ngoba uqukethe ama-lanthanum, i-prateodymium, njll.). Icishe ibe insoluble emanzini ne-acid. Ubuningi obuhlobene 7.3. Iphoyinti elincibilikayo: Ngo-1950 ° C, iphuzu elibilayo: 3500 ° C. Ubuthi, umthamo ongcolile obulalayo (rat, owomlomo) ucishe ube ngu-1g / kg.
ukugcina
Gcina i-Airtight.
Inkomba yekhwalithi
Ihlukaniswe ubumsulwa: ubumsulwa obuphansi: ubumsulwa bungaphakeme kune-99%, ubumsulwa obuphezulu: 99.9% ~ 99.99%, ubumsulwa obuphezulu obungenhla kwe-99.999% ngaphezulu kwe-99.999% ngaphezulu kwe-99.999% ngaphezulu kwe-99.999% ngaphezulu kwe-99.999% ngaphezulu kwe-99.999% ngaphezulu kwe-99.999%
Ihlukaniswe ngosayizi wezinhlayiyana: i-coarse powder, micron, submicron, nano
Imiyalo yezokuphepha: Umkhiqizo ubuthi, anambitha, anambitha, akacasuli, aphephile futhi athembekile, aqinile ekusebenzeni, futhi awenzi ngamanzi nezinto eziphilayo. Kuyinto esezingeni eliphakeme elicacisa i-ejenti, elihlobisa i-ejenti ne-ejenti yamakhemikhali.
sebenzisa
Umenzeli oxinizing. I-catalyst yokusabela kwe-organic. Ukuhlaziywa kwensimbi nensimbi njengesampula evamile yomhlaba evamile. Ukuhlaziywa kwe-Redox Ukuhlaziywa. Ingilazi ehlisiwe. I-Vitreous Enamel Opacifier. Ama-alloys amela ukushisa.
Kusetshenziswe njengesengezo embonini yengilazi, njengokugaya okugayayo kwengilazi yeplate, futhi njengomphumela we-anti-ultraviolet kwezimonyo. Kunwetshwe ukugaya kwengilazi ye-spectacle, i-lens ye-optical, kanye ne-tube yezithombe, futhi kudlala izindima zokuhlobisa, ukucaciswa, kanye nokumuncwa kwama-rays we-ultraviolet kanye nemisebe ye-elektroni yengilazi.
