Hafnium oxide HfO2 foda CAS 12055-23-1
fO2 wani oxide ne na sinadarin nitride, a cikin zafin jiki kuma a ƙarƙashin matsi na al'ada fari ne mai ƙarfi. Marasa narkewa a cikin ruwa, hydrochloric acid da nitric acid, mai narkewa a cikin sulfuric acid da aka tattara da kuma fluorohydroic acid. Ana samun shi ta hanyar bazuwar thermal ko hydrolysis na mahadi irin su vanadium sulfate da chloride oxide. Raw kayan don samar da karfe da vanadium gami. An yi amfani da shi azaman kayan haɓakawa, kayan shafa na anti-radioactive da masu kara kuzari.
