Solid-state synthesis of zirconium nitride and hafnium nitride powders
- Zirconium nitride (ZrN) powders have been prepared by using the zirconium dioxide (ZrO2), sodium azide (NaN3) and metallic magnesium (Mg) as starting materials in a stainless-steel autoclave. The X-ray powder diffraction pattern indicates the formation of cubic phase ZrN. Hafnium nitride (HfN) can also be synthesized from hafnium dioxide (HfO2) through the similar procedure.
