1. High hardness: The hardness of silicon nitride ceramic is second only to diamond and boron nitride ceramic, and it can withstand high physical force and wear.
2. High thermal conductivity: Silicon nitride ceramic has good thermal conductivity and can effectively conduct and dissipate heat, improving the working efficiency and life of the equipment.
3. Corrosion resistance: It can withstand the erosion of corrosive media such as acids and alkalis, and is suitable for harsh chemical working environments.
5. Wide range of uses: Silicon nitride ceramics can be used to manufacture high-temperature parts, cutting tools, silicon nitride ceramic shaft, seals, silicon nitride ceramic ring, etc., and are widely used in aerospace, electronics, chemical industry, machinery and other fields.
In short, silicon nitride ceramics play an important role in harsh environments such as high temperature, high pressure, and corrosion due to their excellent properties and have broad application prospects.
