Chromium(IV) Oxide Description

Chromium (IV) oxide los yog chromium dioxide yog ib qho tsis zoo thermally ruaj khov chromium qhov chaw haum rau iav, optic thiab ceramic daim ntaub ntawv. Tsis tas li ntawd, chomium dioxide yog ib qho hlau nplaum retrievable crystalline xaiv oxidant rau yooj yim cawv thiab hydrocarbons thiab yog siv nyob rau hauv ib co sib nqus cov ntaub ntawv cia tapes.

Oxide compounds tsis ua rau hluav taws xob. Txawm li cas los xij, qee qhov perovskite cov txheej txheem oxides yog cov khoom siv hluav taws xob tshawb nrhiav hauv cathode ntawm cov khoom siv roj oxide thiab cov tshuab tsim hluav taws xob. Lawv yog cov tebchaw uas muaj tsawg kawg yog ib qho oxygen anion thiab ib qho hlau cation. Lawv feem ntau insoluble hauv aqueous daws (dej) thiab ruaj khov heev ua rau lawv muaj txiaj ntsig zoo hauv cov khoom siv ceramic kom yooj yim xws li ua cov tais av nplaum rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hauv lub cev hnyav hauv aerospace thiab electrochemical siv xws li roj hlwb uas lawv nthuav tawm ionic conductivity. Hlau oxide tebchaw yog cov anhydrides yooj yim thiab tuaj yeem ua rau cov kua qaub thiab muaj zog txo cov neeg ua haujlwm hauv cov tshuaj tiv thaiv redox.
