What is the composition of the hexagonal boron nitride structure

White graphite is another name for hexagonal boron nitride. White graphite is the simplest boron nitrogen polymer. Similar to the hexagonal carbon mesh in graphite, nitrogen and boron in hexagonal boron nitride also form hexagonal mesh layers, which overlap each other to form crystals. The crystal is similar to graphite, with diamagnetism and high anisotropy, and the crystal parameters are also quite similar. Boron nitride is mainly used for refractory materials, semiconductor solid-phase doping sources, structural materials for atomic stacks, packaging materials for anti-neutron radiation, rocket engine constituent materials, high-temperature lubricants and mold release agents.

Hexagonal boron nitride

Hexagonal boron nitride is a white crystal with a melting point of nearly 3000°C, high temperature resistance, extremely stable chemical properties, strong acid corrosion resistance, and high electrical insulation properties.

Hexagonal Boron Nitride (h-BN) Overview

Hexagonal boron nitride (h-BN) is an advanced synthetic ceramic that combines many useful thermal, electrical, physical and chemical properties in a unique material. Boron nitride powder, also known as white graphite, is a non-abrasive white powder with a hexagonal flake crystal structure similar to graphite, but has higher oxidation resistance at 800°C. Boron nitride powder has high thermal conductivity, low friction coefficient, high dielectric constant and chemical inertness.

Boron nitride industrial powder is a pure white ceramic material with a hexagonal crystal structure similar to graphite. Boron nitride can withstand temperatures exceeding 2,000°C, and depending on the grade, its dielectric strength is close to 1000 volts/mil. Boron nitride is hot-pressed in the form of blanks, which can be easily processed into rods, rods, plates and even customized shapes.

Boron nitride is the simplest new polymer material. It has hexagonal and cubic crystal form. It is a product with high temperature resistance, corrosion resistance, high insulation and good lubricity. Its oxidation resistance temperature can reach 1000℃ and it has good lubricity. At high temperatures, it is a good high-temperature solid lubricant.

Hexagonal boron nitride (hBN), commonly known as "white graphite", is an artificial ceramic made by reacting boric acid or boron oxide with nitrogen at a temperature above 1600°C. Stability (oxidation resistance at 850°C) and lubricity.

Application of Hexagonal Boron Nitride BN Powder

Hexagonal boron nitride is white (clean appearance), non-toxic and non-conductive. It is an excellent substitute for other commonly used lubricants in metal processing (such as graphite, molybdenum disulfide, organic wax and oil). In most cases, boron nitride can greatly improve the efficiency of these applications.

Hexagonal boron nitride is used as high temperature solid lubricant, extrusion anti-wear additive, ceramic composite material production additive;

Hexagonal boron nitride is used for special electrolysis and resistance materials under high temperature conditions;

Aerospace insulation materials;

Hexagonal boron nitride is used as a release agent for metal forming and a lubricant for metal drawing;

Hexagonal boron nitride is used in molten metal crucibles; radiators and high-temperature insulators;

Hexagonal boron nitride is used as a raw material for cosmetics.
