English alias: Boronnitride off white powder

CAS RN: 10043-11-5

1. sical and chemical properties:

1.1 Molecular formula: BN

1.2 Molecular weight: 24.81(on 1979 international atom weight)

1.3 Structure formula:

1.4 Melting point: 3000?(stable in the inert atmosre)

1.5 Mohs′ hardness: 1-2

1.6 Density: 2.29g/cm3

1.7 Solubility: Insoluble in water.

1.8 Properties: Boron nitride is white, soft and smooth powder that could be similar to the properties of the grate what used to be known as boron mononitride. It has exnt 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.

2. Technical indexes

3. Application: 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-se 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 aluminum 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 sical inert of boron nitrid, but it is stion, inhalation, eye and skin Skin, respiratory system, liver, kidney and the circulatory system may be abnormal by swallow and inhalation. Eye and skin can cause inflammation. Operation must be installed with rubber gloves, a respirator and eye protection by wearing protective clothing.
