Boron nitride, 99.5% (metals basis)


Chemical Properties

BN (hexagonal)
Formula Weight
-325 Mesh Powder
Insoluble in water.


Boron nitride used in the manufacture of high-temperature equipment parts due to its excellent thermal and chemical stability. It is used as a lubricant and an additive to cosmetics, paints, dental cements and pencil leads. It is also used to provide self lubricating properties to ceramics, alloys, resins, plastics and rubbers. In addition to this, it has many industrial applications such as xerographic process, laser printers, oxygen sensors and proton conductors. Cubic boron nitride is used as an abrasive material.


Incompatible with oxidizing agents and water.
