 1. Physical and chemical properties:
1.1Molecular formula: BN
1.2Molecular weight: 24.81(on 1979 international atom weight)
1.3Structure formula:
 
1.4Melting point: 3000℃(stable in the inert atmosphere)
1.5Mohs′ hardness: 1-2
1.6Density: 2.29g/cm3

1.8Properties: Boron nitride is white, soft and smooth powder that could be similar to the properties of the graphite what used to be known as boron mononitride. It has excellent electrical properties of electrical insulating, thermal conductivity, corrosion resistance and good lubrication. In addition, it has corrosion resistance to all melting metals. Its oxidation resistance temperature can reach 1000℃, and can reach 3000℃ when it be used in nitrogen and argon.

 3. Uses: Boron nitride could be extensively used in the industries of petroleum, chemical, machinery, electronics, electric, textiles, nuclear, space and other. It has been used as the additives of plastic resin, the insulators of high-voltage high-frequency point and plasma arc, the solid-phase mixed material of semiconductor, the structural material of atomic reactor, the packing material for preventing neutron radiation, the solid lubricant, wear-resisting material and benzene absorbent, etc. The mixture of titanium diboride, titanium nitride and boron oxide, which is obtained by hot-pressing forming of boron nitride and titanium, is used as the catalyst for dehydrogenation of organic matters, rubber synthesis and platforming. In high temperature, it could be used as the specific materials of electrolysis and resistance, and hot sealing dry-heating agent of transistor. It is the material of aluminium evaporating container. The powder could be also used as the abherent for glass microbead, the release agent of molding glass and metal. 
 4. Safety instructions: With the physical inert of boron nitrid, but it is toxic by ingestion, inhalation, eye and skin contact. Skin, respiratory system, liver, kidney and the circulatory system may be abnormal by swallow and inhalation. Eye and skin contact can cause inflammation. Operation must be installed with rubber gloves, a respirator and eye protection by wearing protective clothing.
 5 Package: Aluminum foil bag with plastic bag, 1 kg net each.
 6. Storage: Store at cool, dry and ventilate. Shelf life of 12 months, if expire, still used if up to standard through retest.
 7. Transportation:Avoid rain, sunlight and crash. Don't mix with strong oxidizer.
