special applications of silicon nitride powder

1. Silicon nitride powder is used for surface treatment of metals and other materials, such as molds, cutting tools, turbine blades, turbine rotors, cylinder inner wall coating, and other alloys.

2. Silicon nitride powder is used in composite materials: such as metal, ceramic and graphite matrix composites, rubber, plastics, coatings, adhesives and other polymer matrix composites, which form a fine diffuse phase in composite materials, good chemical corrosion resistance, especially high temperature resistance, and self-lubricating effect, which greatly improves the comprehensive performance of composite materials.

3. Wear-resistant nanoparticle-based self-lubricating film used for surface protection of mobile phones, advanced automobiles, wear-resistant coatings, electrophoretic paint additives and high wear-resistant performance. Silicon nitride has the characteristics of high hardness and low sliding friction, can be applied to the wear-resistant composite coating of metal surface ceramics, and can also be applied to the coating to reproduce the characteristics of wear resistance and solvent resistance, and high-purity silicon nitride can be used in quartz crucible separating agent.
