Description
1. Silicon slag(off grade silicon) is a by-product when making silicon metal.
2. The silicon content is from 45% to95%, and the rest are C, S, P, Al, SiO2, Fe, Ca etc.
3. The silicon slag is much cheaper than purity silicon metal, and has many industrial applications.
Application
1. It is a good substitute for ferro silicon in steel making which has advantage in reducing the making cost.
2. The silicon slag powder can be made silicon briquette which has far and wide market at home and abroad.
3. It is used as deoxidizer in steel making.
