Boric acid powder typically refers to boric acid particles with a diameter range of 5μm-75μm. This powder is usually obtained through secondary grinding of industrial-grade boric acid.

Hexagonal boron nitride has a layered structure similar to graphite, has good insulation, heat resistance and lubricity, and is often used as a high-temperature lubricating material, electrical insulating material and ceramic reinforcement.

The most widely used boric acid in the world, a colorless crystalline solid. It has a high melting point and boiling point, and is widely used in glass, agriculture, ceramics, medicine, metal processing, petroleum, leather and other industries
