QSAM's Enhanced Boron Nitride Ceramics

Boron nitride ceramics, usually the hexagonal BN only, is a popular machinable ceramic material especially for metallurgy and vacuum chambers. Features of boron nitride material include: high thermal conductivity, machinable, low porosity, electrical insulation, extremely high working temperature in certain atmosphere, low wettability to molten metals and low coefficient of thermal expansion. However, as a soft machinable material, mechanical strength and wear resistance for boron nitride is relatively low. In order to get better mechanical strength, manufacturers of boron nitride ceramic materials (e.g. Saint Gobain, Momentive, QSAM
