English another name: Boronnitride 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)
1.4 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.
1.8 Properties: 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
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.
