Hafnium(IV) nitrate is an inorganic compound, a salt of hafnium and nitric acid with the chemical formula Hf(NO3)4.[2][3][4]
Hafnium nitrate can be prepared by the reaction of hafnium tetrachloride and dinitrogen pentoxide.[5]
Hafnium nitrate is slightly volatile, and can be sublimed at 110 °C and 0.1 mmHg.[6] Hafnium nitrate decomposes on heating (≥ 160°C) to HfO(NO3)2 and then to HfO2.[6]
Hafnium nitrate can be used for the preparation of materials containing hafnium dioxide.[6]
