h- BN powder is a hexagonal crystal, which is a kind of white flake-like fine material similar to graphite, commonly known as white graphite, and excellent in lubrication. BN powder is with lubricity, thermal conductivity and good high temperature performance.
Hexagonal boron nitride is called "white graphite" because it has a layered crystal structure similar to graphite and has similar physicochemical properties to graphite, such as good lubricity and thermal conductivity. h-BN is often used as a sintered ceramic material. Because of its high thermal conductivity, good electrical insulation, low thermal expansion coefficient and non-wettability with most metals, h-BN ceramic has been widely used in high temperature insulation parts, atomic energy, metallurgy, aviation and other fields.
As an advanced ceramic material, boron nitride has many excellent properties such as high temperature resistance, high thermal conductivity, high insulation, machinability, lubrication, non-toxicity and the like, and has strong neutron absorption capacity. Therefore, this new type of inorganic materials will have broad application prospects in the military engineering such as metallurgy, chemical engineering, machinery, electronics, aerospace and so on, and industrial production.
The use of boron nitride high temperature, electrical insulation, h-BN products can be used to make high-temperature plasma welding tools, insulation components, a variety of heater bushings, spacecraft thermal shielding materials. Coupled with the high thermal conductivity, which can be made of coal mine explosion-proof motor insulation heat sink, high temperature thermocouple protection sleeve. The use of h-BN glass, metal melt non-wettability and corrosion resistance, can be used for special smelting smelting a variety of non-ferrous metals, precious metals and rare metals containers, crucibles, pumps and other components.
