Hot-Press Boron Nitride BN Insulation Tubes, Sleeve, And Parts For Vacuum Furnace

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.

The main products of Boron Nitride Ceramics

Hot pressing hexagonal boron nirtride ceramic and boron nitride composite ceramic, includes:

Insulation tubes, sleeve, and parts for vacuum furnace
nozzles for amorphous soft magnetic alloy spray tapes and metal powders gas atomization
horizontal continuous casting separation rings/crystal tubes
crucibles, composite ceramic molds
TiB2/graphite composite ceramic cathodes for electrolytic aluminum
graphite/BN ceramic composite evaporator boats for vacuum evaporation and aluminum plating
large and medium-sized vacuum hot pressing furnaces
large size hot pressing molds, etc.

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.
