Hexagonal Boron Nitride has a microstructure similar to that of
Graphite. In both materials this structure, made up of layers of
tiny platelets, is responsible for excellent machinability and
low-friction properties. we called hexagonal boron nitride (HBN) or
white graphite.

- CABN: Boron Nitride + Calcium Borate
- ALBN: Boron Nitride + Al2BO3
- ZRBN: Boron Nitride + Zirconium Oxide + Boric Oxide (B2O3)
- ZABN: Boron Nitride + Zirconium Oxide + Aluminum Nitride + Al2BO3
- SCBN: Boron Nitride + Silicon Carbon + Al2BO3
Processing of Boron Nitride Ceramics
- Hot Pressed Sintering
- Chemical Vapor Deposition
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.
