The prime features of the boron nitride ceramic sheet

1) Boron nitride is an easier machining technical ceramic than the others, BN ceramic sheet can be machined ideal shape and sizes.
2) Exceptional high-temperature and heat resistance, the max. service temperature under inert reduction atmosphere can be 2800℃
3) Low thermal conductivity and excellent thermal shock resistance, recover one hundred times cycles from 20ºC to 1000ºC free from damage;
4) Chemically and corrosion resistance, It resists many inorganic acids, alkali and extreme wear resistance than graphite

The description of boron nitride ceramic sheet

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.

The application of boron nitride ceramics

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.
