Solid-state synthesis of zirconium nitride and hafnium nitride powders

摘要

Zirconium nitride (ZrN) powders have been prepared by using the zirconium dioxide (ZrO 2 ), sodium azide (NaN 3 ) 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 (HfO 2 ) through the similar procedure.
