Boron Nitride powder

Product Description

Boron nitride is a most simple new type of macromolecular materials with both of hexagonal and cubic crystal shapes. It is a kind of product with high temperature-resisting, corrosion-resisting .high insulating and good  oxidation-resisting temperature can reach ***0, and possesses also good lubricity in high temperature, so it is a  kind of good high-temperature solid lubricants. It has the very powerful capacity of neutron-absorbing. Its chemical properties are stable. It has very powerful capacity of neutron-absorbing, Its chemical properties are stable, It has fairly good corrosion-resisting capacity for various inorganic acids, alkali, salt solutions and organic solvents. It present chemical inert for nearly every melting metals. Its resistance to high temperature can reach ***0, and can reach ***0 when use it in nitrogen and argon. Its forming products possess the fine property easy to machining. Its humid resistance is very good. It has not only low coefficient of heat expansion, but also heat conductivity. It is both good heat conductor and typical electric insulator.
