Cerium dioxide CAS 1306-38-3 yog dab tsi?

Cerium dioxide teeb daj dawb cubic hmoov. Tus txheeb ze ntom ntom yog 7.132. Melting point 2600 ℃. Insoluble hauv dej thiab tsis yooj yim soluble hauv inorganic acids. Cov tshuaj txo qis (xws li hydroxylamine txo cov neeg ua haujlwm) yuav tsum tau ntxiv los pab rau kev sib cais. Nws yog ib qho yooj yim rau nkag mus rau pom lub teeb, tab sis muaj kev nqus zoo ntawm ultraviolet lub teeb, thaum tseem ua rau daim tawv nqaij zoo dua qub.

Daim ntawv thov

Cerium dioxide yog siv los ua ib qho ntxiv hauv kev lag luam iav thiab ua cov khoom sib tsoo rau iav daim hlau. Nws tau raug nthuav dav rau cov iav tsom iav, qhov muag qhov muag, thiab cov kab hluav taws xob cathode, thiab muaj kev ua haujlwm xws li decolorization, clarification, absorption ntawm ultraviolet thiab electron rays hauv iav. Kuj tseem siv los ua tus neeg saib xyuas kev cuam tshuam rau cov tsom iav qhov muag, cerium titanium daj yog tsim nrog cerium kom muab cov iav xim daj. Siv los ua tus neeg sawv cev impregnating rau piezoelectric ceramics hauv ceramic glazes thiab kev lag luam hluav taws xob. Nws kuj tseem siv los tsim cov khoom siv hluav taws xob uas muaj zog heev, cov npog npog rau cov roj teeb, thiab cov ntxaij vab tshaus fluorescent rau X-rays.
