Silicon slag 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, SiO2, Fe;The silicon slag is
much cheaper than purity silicon metal, and has many industrial
1.It is a good substitute for ferro silicon in steel making, which
has advantage in reducing the making cost and
2. It is used to be made silicon briquette which has far and wide
market at home and abroad.
3. It is used as deoxidizing agent in steel making 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.
