The appearance is a white loose powder with a soft and smooth texture. It belongs to the hexagonal crystal system and has a sheet-like structure. This product has good electrical insulation, thermal conductivity, chemical corrosion resistance, and lubricity, and is stable to almost all organic solvents, molten metals, and corrosive chemicals

Hexagonal boron ammonium-H type has good electrical insulation, thermal conductivity, chemical corrosion resistance, and lubricity, and has strong neutron absorption ability. It is relatively stable to almost all organic solvents and corrosive chemicals; It exhibits chemical reactivity towards almost all molten metals. Below 1000 ℃ in the air, various physical and chemical properties remain basically unchanged; It remains stable when used at a temperature of 3000 ℃ in nitrogen or argon gas. Hexagonal boron nitride H-type powder is hot pressed and sintered into white blocks, which are easy to machine and can withstand temperatures up to 2000 ℃
