Material Applications
Suitable as a release agent for metal forming and a lubricant for metal wire drawing.
Suitable as a special electrolytic and resistive material under high-temperature conditions.
Suitable as a high-temperature solid lubricant, anti-wear additive, additive for ceramic composite production, refractory material, and antioxidant additive.
Suitable as a desiccant for transistor heat sealing and an additive for polymer materials such as plastic resins.
Pressed boron nitride products in various shapes can be used as high-temperature, high-pressure, insulating, and heat-dissipating components.
Suitable as a thermal shielding material in aerospace and aviation applications.
Under the presence of a catalyst, it can be transformed into cubic boron nitride (CBN)—a material as hard as diamond—through high-temperature and high-pressure processing.
