Silicon Metal (Si Metal) is high purity silicon, also known as industrial silicon or crystalline silicon 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", It is mainly used as an additive for non-ferrous alloys and is an indispensable basic raw material for many high-tech industries. Silicon metal is divided into different grades according to the different content of iron, aluminum and calcium, such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101.
