Metallurgical Grade Si Metals

Metallurgical Grade Si Metal is produced by the carbothermic reduction of silica (presented as either quartz or quartzite) in electric furnaces.It is silver gray or dark gray with metallic luster. It has high melting point, heat resistance, high resistivity and good resistance to oxidation.  It is mainly used for aluminum ingot smelting, silicon steel, aluminum alloy materials and special steel smelting and other products.

The main grades our products cover:

Grade	Si	Fe(max)	Al(max)	Ca(max)	P(max)
