Hexa-Boron Nitride CAS 10043-11-5 Manufacture

Product Description

 

Executive standard: Q/TY.J08.04-2015

 

English alias: Boron nitride off white powder

 

CAS RN: 10043-11-5

 

1. Physical 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 atmosphere)

 

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 excellent 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. Physical 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℃.

3. Application: H-BN-A: It has excellent heat resistance and oxidation resistance. Its original particle size is small, reunion size is large. With spherical particle, it has been used as filler, the releasing agent for casting forming and injection molding.

 

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 excellent 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.

 

H-BN-C and H-BN-D: High crystallinity. It is epigranular. High-purity H-BN has excellent 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.

 

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 Packing: Aluminum foil bag lined with plastic bag, net weight 1 kg/bag.

 

6. Storage: Store at cool, dry and ventilate. The shelf life is 12 months after manufacturer date. It is still available if retest result is qualified after expire date

 

7. Transportation: A Avoid water, exposure and violent collision .Do not transport with strong oxidizers.
