Boron Nitride Powder

Boron nitride is a man-made ceramic material prized for its excellent thermal and chemical stability and lubricating properties.

Kennametal boron nitride powder is non-toxic and exhibits high electrical resistivity and temperature stability. It is oxidation resistant under inert atmospheres of temperatures up to 2200oC.

Our boron nitride powder can be used in products ranging from high-temperature lubricants to cosmetics.
