What is hafnium nitride crystal structure?

Hafnium Nitride (HfN) Powder is a gray powder with a cubic crystal structure. Melting point 3310℃, microhardness 16GPa.  It’s an important component of hafnium alloy. Hafnium Nitride is fairly stable but easily corroded by aqua regia, concentrated sulfuric acid, and hydrofluoric acid. The reaction is generated directly by the hafnium and nitrogen at 900 ℃, it is an important part of refractory compounds hafnium alloy.

Typical Applications

Hafnium Nitride has excellent mechanical, electrical, optical, high temperature and corrosion resistance characteristics, and has very important applications in the field of mechanical manufacturing and microelectronics.

Nano Hafnium Nitride 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, and can be used in aerospace key optical devices.

HfN is a new type of hard material with high melting point, high hardness, wear resistance and oxidation resistance.  It creates an abrasion-resistant, chemically inert outer film for cutting tools, a high temperature-resistant protective film with high hardness, wear resistance, and oxidation resistance.
