Kodi Cerium dioxide CAS 1306-38-3 ndi chiyani?

Cerium dioxide kuwala chikasu woyera kiyubiki ufa. Kachulukidwe wachibale ndi 7.132. Malo osungunuka 2600 ℃. Insoluble m'madzi ndipo sasungunuka mosavuta mu ma inorganic acid. Zochepetsa (monga hydroxylamine reduction agents) ziyenera kuwonjezeredwa kuti zithandizire kusungunuka. Ndikosavuta kulowa mkati mwa kuwala kowoneka bwino, koma kumayamwa bwino kwa kuwala kwa ultraviolet, komanso kumapangitsa khungu kukhala lachilengedwe.

Kugwiritsa ntchito

Cerium dioxide imagwiritsidwa ntchito ngati chowonjezera mumakampani agalasi komanso ngati chogawira mbale zamagalasi. Yakulitsidwa kuti ipere magalasi agalasi, magalasi a kuwala, ndi machubu a cathode ray, ndipo ili ndi ntchito monga decolorization, kumveketsa bwino, kuyamwa kwa ultraviolet ndi kuwala kwa ma elekitironi mugalasi. Imagwiritsidwanso ntchito ngati anti reflective agent ya magalasi agalasi, cerium titanium yellow imapangidwa ndi cerium kuti galasilo likhale lachikasu chopepuka. Amagwiritsidwa ntchito ngati inpregnating agent kwa piezoelectric ceramics mu ceramic glazes ndi makampani amagetsi. Amagwiritsidwanso ntchito popanga zida zogwiritsira ntchito kwambiri, zovundikira za nyali zamagesi, komanso zowonetsera fulorosenti za X-ray.
