Boron Nitride Powder

Hexagonal boron nitride is a kind of loose white powder, similar to the properties of graphite, which has known as the "white graphite". It has good electrical insulation, thermal resistance and chemical resistance; anti-oxidation temperature can up to 900. Because hexagonal boron nitride has low coefficient of thermal expansion and high thermal conductivity, its thermal shock resistance is excellent. Solid Boron Nitride with a variety of excellent performance that can be widely used in high-voltage high-frequency electric insulators and plasma arc, automatic welding temperature frame coating, high frequency induction furnace materials, semiconductor phase admixture, atomic reactor construction materials, packaging materials to prevent neutron radiation, radar transfer window, the media radar antenna and composition of rocket engines and so on.

Hexagonal boron nitride (HBN) has a high thermal conductivity, low dielectric constant and dielectric loss, reliable electrical insulation properties, low coefficient of thermal expansion, good thermal shock resistance, excellent processing performance, for most metals are not invasive, light, infrared and microwave-transparent, and has very high heat resistance, excellent performance, which is an important aerospace materials that has been widely used in launch vehicles, spacecraft, missiles, satellites and other spacecraft radio system. This new material has many excellent properties with hardness better than diamond crystal, tougher than commercial carbide, and cubic boron nitride anti-oxidation temperature higher than the single crystal itself, HBN is expected to become a new generation of steel materials processing industry in the tool material so there is no doubt that it has broad application prospects.
 

Packaging

• we make the closed packing with double anti-static bag or aluminum foil bags inside, and with carton outside.
• If in bulk, we pack the goods with moisture-proof lastic bag inside, and with 25 kilograms paper barrel outside .
