Boron Nitride 99% 99.8% 100-200nm 0.3um 2um 3um Hexagonal Boron Nitride powder
Products Description
Hexagonal boron nitride powder is a material showing excellent thermal conductivity, heat and corrosion resistance, electric insulation, lubrication/demolding performance, and used as an additive to various types of matrixes. Also, BN coating agent is used as heat resistant demolding material for various types of metal/glass by making use of its corrosion resistance and demolding characteristics.
Features: Good electrical insulation, thermal conductivity, chemical corrosion resistance and lubricity.
The heat conduction, insulation, lubrication, high temperature resistance and molten metal corrosion resistance of hexagonal boron nitride with high crystallinity are better than ordinary products.

Application
- Superhard material industry.
Used for the preparation of cubic boron nitride. Lithium-based or magnesium-based catalysts, can be converted into cubic boron nitride under ultra-high pressure and high temperature conditions.
- Coating industry.
HBN can make the metal or ceramic material have good surface lubricity and anti-sticking properties, and can prevent or reduce the chemical reaction between the material and the melt, and improve the life of the material. It can be used in all kinds of radiators, electronic parts to increase heat dissipation. And it’ s suitable for optoelectronic industry radiators, electronic parts cooling modules, power cooling modules, automotive radiators, oil coolers, transmission oil coolers, and other types of coolers.
- Electronic materials industry.
When used as a filler for high thermal conductivity materials, HBN has excellent heat resistance, good corrosion resistance, low thermal expansion coefficient and high heat rate. It is the most suitable thermal insulation material, which can improve the thermal conductivity of resin-based electronic components.
- High-end cosmetics industry.
When used as a high-end cosmetic filler, it can increase cosmetic adhesion and covering performance, and has a good greasy feel, making makeup products firm, easy to apply, easy to clean and remove, and harmless to the human body.
- Lubricating material industry.
As an additive for solid and liquid lubricating materials, it can improve fuel efficiency, the wear resistance of oil cylinders, and have a significant energy saving effect.
- High-tech ceramic industry.
Used to prepare HBN agglomerates.HBN agglomerates have high thermal conductivity, excellent high temperature performance, excellent electrical insulation and dielectric properties, and are often used to prepare high temperature and high pressure heat dissipation components, high temperature electrical insulation devices, crucibles and molds, as well as high permeability and high stability microwave antenna window and other components.
