Hafnium Nitride Powder (HfN), CAS No 25817-87-2

Hafnium Nitride Powder (HfN), CAS No 25817-87-2

Hafnium nitride powder, also known as HfN, is a refractory material that exhibits excellent mechanical, thermal, and electrical properties. It is a binary compound composed of hafnium and nitrogen.

Hafnium nitride powder is produced through a reaction between hafnium metal or hafnium oxide and nitrogen gas, typically via a thermal reduction process. The resulting powder is a dark gray or black solid material with a high melting point and high hardness.

Hafnium nitride powder is used as a protective coating for cutting tools, as it exhibits excellent wear resistance and thermal stability at high temperatures. It is also used as a component in ceramic cutting tools, as well as in the manufacture of refractory ceramics for high-temperature applications.

Hafnium nitride powder has potential applications in the field of electronics, particularly as a gate electrode material for high-performance transistors due to its high thermal stability and low electrical resistance. It also has potential uses in the aerospace and defense industries due to its excellent mechanical and thermal properties.

Overall, hafnium nitride powder is an important material with a wide range of industrial applications, particularly those requiring high-performance materials that can withstand extreme conditions.

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.
