Hexagonal boron nitride-H type has good electrical insulation, thermal conductivity, chemical resistance and lubricity. And has a strong neutron absorption capacity. It is relatively stable to almost all organic solvents and corrosive chemicals. It is chemically inert to almost all molten metals. Below 1000°C in the air, various physical and chemical properties remain basically unchanged. The temperature of 3000℃ is still stable in nitrogen or argon. The hexagonal boron nitride-H type powder is hot-pressed and sintered into a white block shape, which is easy to machine and can withstand a temperature of up to 2000°C.
The performance is close to the advanced level of similar foreign products.
H-BN-A, B, C: It is a medium crystal. Because the particles are spherical, they are particularly suitable as a release agent for casting, casting and injection molding, and composite ceramics. They are also easy to hot press.
H-BN-D: Due to its similar particle size to PTFE and uniform particle size, it is especially suitable for high-pressure switch nozzles; it is also suitable for heat-conductive plastics or heat-conductive rubber; and because of its low oxygen content (generally less than 0.5%) It is also especially suitable as a special ceramic raw material.
H-BN-E: High crystallinity of hexagonal boron nitride has better performance than ordinary products. Can be used in a variety of high-end areas, including cosmetics and thermal materials.
H-BN-F: Often used as an additive in the high-end electronics industry. Currently, other application areas of this product are being developed.
Popular areas of boron nitride applications · Skin care products and makeup products · Epoxy resin · PVC plastic · Silica gel heat conduction · Lubricating oil · Cubic boron nitride · Used as the main raw material for vacuum aluminized evaporation boat · Used for making hot-pressed ceramic parts · Used as raw material for special ceramics · mold release agent（boron nitride coating） · Used for the preparation of cubic boron nitride
