Product Description

About-silicon slag

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

2. The silicon content is from 45% to 95%, 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.

Function-Silicon Metal Silicon Slag

Use as deoxidizing agent in the production of magnesium, chromium and other metals via the same mechanism.Used in the production of lower grade of Si3N4 in a cost effective manner, the material is suitable for refractory applications such as refractory bricks and other high-temperature applications.

Application:

1. Silicon content from 30~50% is used for silicon addition for iron making in the blast furnace and cupola, 50~70% is used for the deoxidization of steel making.
2. Silicon Slag can used as Silicon metal alternative.
3. We use silicon slag to produce silicon briquette which is far and wide market in domestic and international.
4. Silicon slag is a good substitute of FeSi in steel making, which has advantage in reducing the cost of production.
