Hexagonal boron nitride is a good conductor of heat, an electrical insulator, and has the lubricating properties of a wolf. Therefore, hexagonal boron nitride is widely used in ceramic manufacturing, such as crucibles, evaporation boats for aluminum plating, circuit board substrates and high-temperature lubricants industries, and is used in the preparation of hexagonal boron nitride and can also be used as an atomic reactor. Structural materials and rocket engine blocks.H-BN-C (3-5μm): it has small particle size, high crystallinity, suitable for applications with small particle size requirements, such as thermal tape and thermal film additive; thermal fiber product additives; demoulding Used as a preparation for cubic boron nitride; special ceramic raw materials.
