Silicon Slag(Silicon Metal Slag)is a by-product from the manufacture of silicon metal. It is a kind of mixture which contains the main content Silicon (35%~65%) and other components such as C, S, P, Al.etc.
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 markets in domestic and international.
