Product Description

Silicon slag

1. Silicon slag(off grade silicon) is a by-product when making silicon metal. 

2. The silicon content is from 30% to 65%, 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.
