DESCRIPTION

Silicon metal is silver gray or dark gray powder with metallic luster, which be of high melting point, good heat resistance, high resistivity and superior oxidation resistance, it’s called “industrial glutamate”, which is an essential basic raw material in hi-tech industry. As an alloy element in smelting ferro silicon in the steel industry, and as a reducing agent in many kinds of metal smelting.
