The structure of boron nitride ceramic is similar to that of graphite. It's commonly known as white graphite. Therefore, boron nitride ceramic owns great heat resistance, high temperature dielectric strength,thermal stability, thermal conductivity, and is an desirable heat dissipating material and high temperature insulating material. Besides, it has good chemical stability and good self-lubricating properties. Boron nitride ceramic parts, such as boron nitride ceramic sheet, Boron nitride ceramic tube have low hardness and can be machined with an accuracy of 0.01 mm.
Boron nitride ceramics are widely used in the manufacture of semiconductor heat-dissipating insulation parts, high-temperature containers for metallurgical melting, high-temperature bearings, and glass forming molds.
