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℃.

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.
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. 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.
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.
