Product Overview
Description
High purity Hexagon Boron Nitride BN Powder
Product Description
Product performance：
The melting point of boron nitride is 3000 ℃, the density is 2.25g /cm3, the appearance is white loose powder with soft texture and smooth feeling, which is similar to the nature of graphite, belonging to hexagonal crystal system and sheet structure. So it is called "white graphite". This product has good electrical insulation, thermal conductivity, chemical corrosion resistance and lubricity, and has strong neutron absorption capacity. It is stable to almost all organic solvents and corrosive chemicals; Hexagonal boron nitride is chemically inert to almost all molten metals, and its physical and chemical properties remain basically unchanged below 1000 ℃ in air; It is still stable at 3000 ℃ in inert gas. Hexagonal boron nitride powder becomes white block after hot pressing and sintering, which is easy to machine, and the temperature resistance can be as high as 2000 ℃.

Performance characteristics:
1: HC grade products are sintered at 1600-1800 ℃, with medium crystallization, excellent high temperature resistance and oxidation resistance, small original particle size and large agglomeration particle size. Because the particles are spherical, they are particularly suitable for filling, mold release agent for casting and injection molding and composite ceramics, and are also easy to be hot pressed.
2: The HN grade product is sintered at 1800-2000 ℃, and its performance reaches or approaches the advanced level of similar foreign products. The HN grade product is especially suitable for high-voltage switch nozzle because its particle size is similar to that of polytetrafluoroethylene and its particle size is uniform; At the same time, because of its excellent thermal conductivity, it is very suitable to be used as thermal conductive plastic or thermal conductive rubber; Because of its low oxygen content (generally less than 0.5%), it is also particularly suitable for special ceramic raw materials.
3: HS grade hexagonal boron nitride products are also sintered at 1800-2000 ℃, with high crystallinity and more uniform particle size. 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. It can be used in various high-end fields, including cosmetics and thermal conductive materials, and its performance reaches or approaches the advanced level of similar foreign products.
4: HF grade hexagonal boron nitride products have small particle size, high crystallinity, high purity and low content of water-soluble boron oxide, which are suitable for the application of products with small particle size requirements.
