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