Hafnium oxide HfO2 hmoov CAS 12055-23-1
fO2 yog ib qho oxide ntawm cov khoom nitride, ntawm chav tsev kub thiab nyob rau hauv qhov siab ib txwm yog cov khoom dawb. Insoluble hauv dej, hydrochloric acid thiab nitric acid, soluble hauv concentrated sulfuric acid thiab fluorohydroic acid. Nws yog tau los ntawm thermal decomposition lossis hydrolysis ntawm cov tshuaj xws li vanadium sulfate thiab chloride oxide. Cov ntaub ntawv raw rau kev tsim cov hlau thiab vanadium alloys. Siv ua cov ntaub ntawv refractory, cov tshuaj tiv thaiv radioactive thiab catalysts.
