Explanation
Boron nitride crystal belongs to hexagonal crystal system, which is similar to graphite in structure and performance, so it is also called "white graphite". It has good heat resistance, thermal stability, thermal conductivity, high temperature dielectric strength, and is an ideal heat dissipation materials and high temperature insulation materials. Boron nitride has good chemical stability and can resist erosion by most molten metals. It also has good self-lubrication. boron nitride product have low hardness and can be machined with an accuracy of 1/100mm.
