1.Silicon slag/scrap/particle/powder is a by-product from the manufacture of silicon metal, it is a kind of mixture which contains the main content Silicon (45%~95%) and other components such as C, S, P, Al, Fe.
2.It is a good substitute for FeSi in steel making, which has advantage in lowing the cost of production and reusing resource. Usually we use silicon slag to produce silicon briquette which is far and wide market in domestic and international.
3.Advantage
low the cost of production,reuse resource
increase the flow of molten iron slag effectively
improve furnace temperature

5.Application
The silicon slag is much cheaper than ≥99% purity silicon metal, and has many industrial applications.
It is Used as deoxidizing agent in steel production to reduce oxygen levels in the melt via reaction .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;
