Silicon slag is a by-product of smelting metal silicon and ferrosilicon.It is a kind of scum floating on the furnace in the process of smelting silicon.It’s content is from 45% to 70%,and the rest are C,S,P,Al,Fe,Ca. It is much cheaper than purity silicon metal. Instead of using ferrosilicon for steelmaking, it can reduce the cost.
Silicon Metal is also called industrial silicon or crystalline silicon. It has high melting points, good heat resistance and high resistivity. It is used to manufacture steel, solar cells, and microchips. Also used to produce silicone and silane, which are in turn used to make lubricants, water repellents, resins, cosmetics, hair shampoos and toothpastes.

Ferro Silicon is mainly used as a deoxidizer in the steel making industry, in order to obtain chemical composition of qualified steel and to improve the quality of steel. Also it is used as inoculants and nodulizers in the cast iron industry and as a reducing agent in ferro alloy production. In addition it is used as welding electrode coating in the electrode manufacturing industry.
