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, slightly soluble in hot acid.

1.8 Properties: Hexa-boron nitride has exnt electrical properties of electrical insulating, thermal conductivity, corrosion resistance and good lubrication. It has the strong ability of neutron absorption. With chemical properties of stability, it has corrosion resistance to various inorganic acids, alkali, salt solutions and organic solvents. So does all melting metals. sical and chemical properties unchanged under 1000?. The temperature can reach 3000? when used in nitrogen and argon. H-type hexa-boron nitride powder is autoclaved to become white block, and easy to processing. Heat resistance temperature reaches 2000?.

2. Technical indexes

H-BN-C and H-BN-D: High crystallinity. It is epigranular. High-purity H-BN has exnt properties of heat conductivity, insulation, lubrication, high temperature resistance and molten metal resistance. It has been use at the top field, include maquillage and heat conductive material. H-BN-B: The properties of products reach or approach advanced international standards. As the particle size is uniform closed to polytetrafluoroethylene, it has been used in the ejector of high-voltage switch. With exnt thermal conductivity, it has been used in thermal conductive plastics and rubbers. With low oxygen levels (<0.5%), it has been used to prepare the special ceramic materials. 3. Application: H-BN-A: It has exnt heat resistance and oxidation resistance. Its original particle size is small, reunion size is large. With srical particle, it has been used as filler, the releasing agent for casting forming and injection molding.

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.
