Boron nitride is a crystal composed of nitrogen atoms and boron atoms. Chemical composition of 43.6% boron and 56.4% nitrogen in four different variants: hexagonal boron nitride (HBN), rhombohedral boron nitride (RBN), cubic boron nitride (CBN) and wurtzite nitrogen Boron Nitride (WBN). Its cubic crystalline variant is considered the hardest known substance. (Its Vickers hardness reaches 108 GPa, while the Vickers hardness of synthetic diamond is 100 GPa.
Boron Nitride Properties
Boron nitride has a variety of excellent properties, and is widely used in high-voltage high-frequency electricity and plasma arc insulators, coatings for automatic welding high-temperature resistant frames, materials for high-frequency induction furnaces, solid-phase admixtures for semiconductors, and the structure of atomic reactors Materials, packaging materials to prevent neutron radiation, radar transmission windows, radar antenna media and rocket engine components, etc. Due to its excellent lubricating properties, it is used as a high temperature lubricant and as a release agent for many models. Molded boron nitride can be used to manufacture high temperature resistant crucibles and other products.
Excellent thermal shock resistance
High electrical resistivity – excluding aerosols, paints, and ZSBN
High thermal conductivity
Anisotropic (thermal conductance is different in different planes relative to pressing direction)
Good chemical inertness
High temperature material
High dielectric breakdown strength, >40 KV/mm
Low dielectric constant, k=4
Some of the most common boron nitride applications we complete include:
Furnace fixture supports and components
Melting crucibles for glass and metals
Plasma and welding tip insulators
High temp thermal complete systems
Molten metal carrier pipes
Nuclear reactor shields and linings
Heat radiation shielding
Transistor heat sinks
Ceramic coating and paints
Refractory molds for glass forming and titanium forming
Ceramic electrical insulators
Thermocouple protection sheaths
