The performance of silicon nitride powder:
1. Silicon nitride powder has good corrosion resistance, thermal shock and wear resistance. It can be used at temperatures of 1900 degrees Celsius.
2. Has excellent endurance split very stable chemical composition and thermal conductivity.
3. The product contains anitride, having a small expansion coefficient, heat conductivity and strength,almost no heat shrinkage characteristics.
4. Strength and resistance toconsume large.
5. High-temperature good oxidation resistance, the surface layer of oxide film after prolonged use, and protect the inner material not affected by chemical reactions.
Applications for silicon nitride powder:
Silicon nitride powder iswidely used in high-tech structural ceramics, wear-resistant materials,refractory materials, and many other fields. For example:
1. Metallurgy areas: silicon nitride as a new refractory materials used in metallurgy furnace, furnace mouthsealed, blast furnace outlet, hooks amorphous materials and steel industry inthe nitrogen additives.
2. Machinery Industry: silicon nitride ceramic bearings used for ball, roller, ball seat, tool and die, newceramic knives, pump plunger mandrel sealing materials.
3. Chemical industry: silicon nitride ceramics are used as wear and corrosion components, such as valve,pump, carburetor combustion, filters and so on.
