Hafnium Nitride Powder Production Process

Produced by a direct reaction of hafnium and nitrogen at 900℃, or by a reaction of hafnium halides and ammonia or a mixture of nitrogen and hydrogen. Hafnium alloy is an important component of the refractory compound.

Hafnium Nitride Powder Application

Hafnium nitride powder has excellent mechanical, electrical, optical, high temperature, and corrosion resistance characteristics, and has very important applications in the field of mechanical manufacturing and microelectronics. Hafnium nitride nanometers can be widely used in semiconductor, photoelectric, and machining fields. Because of the integration of a variety of excellent mechanical, thermal, optical, and corrosion wear resistance characteristics, the hafnium nitride nanometer film is expected to become an efficient optical window anti-reflection protection coating material, that can be used in aerospace key optical devices. HfN is a new type of hard material with a high melting point, high hardness, wear resistance, and oxidation resistance. It can be used as a protective layer for technical and decorative fields, abrasion-resistant outer film for cutting tools, chemical inert film, and high temperature resistant protective film.
