Quick Facts Names, Identifiers ...

Synthesis

Hafnium nitrate can be prepared by the 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]
