Applications of Boron Nitrides Ceramics

. Thermal Management
Excellent electrical insulation and thermal conductivity make BN very useful as a heat sink in high-power electronic applications. Its properties compare favorably with beryllium oxide, aluminum oxide, and other electronic packaging materials, and are easier machinable to desired shapes and sizes.
. High Temperature Environments
Temperature stability and excellent resistance to thermal shock make BN the ideal material in the toughest high-temperature environments such as equipment for plasma arc welding, diffusion source wafers, and semiconductor crystal growth equipment & processing.
. Molten Metal Handling
BN is inorganic, inert, nonreactive with halide salts and reagents, and is not wet by most molten metals and slags. These characteristics, combined with low thermal expansion, make it ideal for interface materials used in various molten metal processes.
