Silicon nitride powder is a white-gray powder with a density of 3.2g/cm³. It has many functions and can be used in different fields. As a new type of refractory material, silicon nitride powder is used in metallurgical furnace bodies, furnace mouth seals, ironmaking furnace water outlets, iron hook amorphous materials, and nitrogen additives in the steelmaking industry.

1. It has good corrosion resistance, thermal shock and wear resistance. Can be used at temperatures below 1900 degrees Celsius.
2. It has excellent splitting resistance, very stable chemical composition and thermal conductivity.
3. Silicon nitride powder contains nitride, which has the characteristics of small expansion rate, high thermal conductivity and strength, and almost no shrinkage when heated.
4. High strength and durability.
5. It has good high-temperature oxidation resistance. After long-term use, an oxide film will form on the surface and protect the internal materials from chemical reactions.
