1.8 Properties: 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 lubricity. Its
Oxidation-resisting temperature can reach 1000° C, 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 2000° C, and can reach 2800° C 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.
