Cov yam ntxwv ntawm cov khoom:Radon dioxide (HfO2) yog ib qho oxide ntawm cov khoom nitride, nyob rau hauv chav tsev kub thiab nyob rau hauv ib txwm siab yog ib tug dawb khoom. Cov hmoov dawb, nrog peb cov qauv siv lead ua: ib qho oblique, quad thiab cubic, melting point 2780 txog 2920K. Boiling point 5400K. Lub coefficient ntawm thermal expansion yog 5.8 × 10-6 ° C. Insoluble nyob rau hauv dej, hydrochloric acid thiab nitric acid, soluble nyob rau 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 los ua cov ntaub ntawv refractory, anti-radioactive coatings thiab catalysts.
