Note: It can be customized into 10- 100mm or 0- 200mesh in lump, grain and powder.
Applications
The product is suitable for casting industry such as stainless steel smelting, special alloy steel smelting, oriented stainless steel smelting.
As a new refractory material, it is used in the metallurgy field, such as metallurgical furnace,furnace mouth sealing, iron-fining furnace outlet, iron hook and amorphous materials, and nitrogen additive in the steelmaking industry.
Silicon nitride can be used as a high-efficiency abrasive material in making of abrasive tools,as well as in the chemical industry of acid resistance, alkali resistance, corrosion resistance, etc.
