供应Hexagonal boron nitride has good heat resistance (it can withstand temperatures up to 2300°C in an inert gas atmosphere, and the theoretical temperature resistance can reach 3000°C), thermal stability, thermal conductivity, and high - temperature dielectric strength. It is an ideal heat - dissipating material and high - temperature insulating material. Boron nitride has good chemical stability, can resist the erosion of most molten metals, and at the same time, it also has good self - lubricity and good machinability.
