silicon metal
Silicon metal is one of main raw materials used for steel making additive in metallurgy and foundry field 3303#,553#,441#,2202
Silicon metal
Industrial silicon is also called silicon metal.It is silver gray or dark gray with metallic luster.It has the feature of high melting point,good heat resistance,high resistivity and superior oxidation resistance,it is called "industrial glutamate",which is an essential basic raw material in hi-tech industry.Product made of it are applied in steel smelting furnace,kiln hood and kiln furniture etc.
