Hafnium(IV) nitrate is an inorganic compound, a salt of hafnium and nitric acid with the chemical formula Hf(NO3)4.[2][3][4]
Synthesis[]
Reaction of hafnium tetrachloride and dinitrogen pentoxide.[5]
Properties[]
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]
Applications[]
Hafnium nitrate can be used for the preparation of materials containing hafnium dioxide.[6]
