Hot-Press Boron Nitride BN Ceramic Horizontal Continuous Casting Separation Rings And Crystal Tubes

Boron nitride belongs to the hexagonal system. Its structure is similar to graphite, and their properties are also similar. Therefore, it is also called " white graphite". It has good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and is an ideal heat dessipating material and high temperature insulatiing material. Mohs Hardness 2 can be processed into various shaped parts.

Performance

The oxidation resistance temperature is 1000℃, which can replace graphite products.
Metal corrosion resistance, no wetting, long service life.
The product has high density, good mechanical strength, does not react with most active metals, and has good chemical stability.

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
