What is Hexagonal Boron Nitride BN Powder CAS 10043-11-5:
Hexagonal boron nitride (h-BN) is a compound composed of nitrogen and boron atoms and is generally considered a very important ceramic material. Boron nitride exists mainly in three crystalline forms: hexagonal boron nitride, cubic boron nitride, and wurtzite boron nitride.
The hexagonal Boron Nitride formula is h-BN, an advanced synthetic ceramic that combines several useful thermal, electrical, physical, and chemical properties in one unique material.
Boron Nitride powder, also called white graphite, is a non-abrasive, white powder with a hexagonal platy crystal structure similar to graphite but a much higher oxidation resistance at 800ºC. Boron Nitride thermal conductivity is high, and BN has a low coefficient of friction, high dielectric constant, and is chemically inert.
Boron nitride industrial powder is a pure white ceramic material with a hexagonal crystal structure similar to graphite. The boron nitride melting point is 2973 ºC. 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 as billets, which can be easily processed into rods, bars, plates, and customized shapes.

Characteristics of hexagonal boron nitride
Structural characteristics: Hexagonal boron nitride has a layered structure similar to the graphite structure, in which each boron atom is connected to three nitrogen atoms, and each nitrogen atom is connected to three boron atoms. This layered structure gives hexagonal boron nitride good planar stability and high interlayer shear strength.
Physical Properties: The hexagonal boron nitride crystal structure is a hexagonal crystal system with a high hardness and melting point. Its hardness is second only to diamond, and its melting point is about 3000℃. Hexagonal boron nitride is a white or slightly yellow solid insoluble in water. It does not react with acids and alkalis but can react with oxidizing agents to produce boric acid and nitrogen at high temperatures.
Chemical Properties: Hexagonal boron nitride has high chemical stability and does not generally react with acids and bases or oxidizing agents. However, at high temperatures, hexagonal boron nitride can react with certain metal oxides to generate composite oxides, which offers the possibility of its application in ceramic materials.

Applications of hexagonal boron nitride
Coating materials: Because of its high hardness and melting point, hexagonal boron nitride is widely used in coating materials. In the field of cutting tools, hexagonal boron nitride coating can improve tools' wear resistance and service life. In addition, hexagonal boron nitride coatings are widely used in optical instruments, electronic equipment, and automobiles.
High-temperature structural materials: Hexagonal boron nitride has excellent high-temperature resistance and chemical stability, so it is widely used in high-temperature structural materials. For example, hexagonal boron nitride can manufacture high-temperature furnaces, combustion chambers, turbine blades, and other high-temperature structural components in aerospace, automotive, petrochemical, and other fields.
Synthetic polymer materials: Compounding hexagonal boron nitride with polymer materials can prepare polymer composites with excellent performance. For example, composite materials with high thermal conductivity can be prepared for heat dissipation of electronic equipment by compositing hexagonal boron nitride with polyimide.
Optical materials: hexagonal boron nitride has high transmittance and refractive index; other characteristics can be used as optical materials. In optical components, hexagonal boron nitride can be used as window materials, mirrors, etc., to improve the performance of optical systems.
Catalyst carrier: Hexagonal boron nitride has high activity and good selectivity and can be used as a catalyst carrier. For example, metal catalysts can be loaded onto hexagonal boron nitride carriers in hydrogenation reactions to improve catalyst dispersion and activity.
Electronic Packaging Materials: Because of its high thermal conductivity and good insulating properties, hexagonal boron nitride is widely used in electronic packaging. In electronic packaging, hexagonal boron nitride can be used as thermal conductive and insulating material to improve the reliability and stability of electronic equipment.
