Boron nitride (BN) disk has a high melting point, thermal conductivity, good insulation properties, high flexural strength, good thermal shock resistance, resistance to chemical corrosion. At elevated temperatures with relatively stable high frequency dielectric properties. BN is the most unique advantages with excellent machining properties can be processed into a form of complex, high precision ceramic pieces. It is widely used composite conductive ceramic evaporation boat, crucible temperature, sputtering target, high-temperature and high-frequency plasma arc of an electrical insulator, the electronic module cooling device, traveling wave tube and collection fins, fin transistors, heat dissipation board semiconductor package, high frequency induction furnace atomic reactor materials and structural materials, anti-Optical radiation, radiation chemistry, nuclear radiation materials and radar transfer window.
