Silicon metal (Si metal) is high purity silicon, also known as industrial silicon or crystalline silicon. Although silicon metal is a non-metal, it has a metallic luster on the outside. It has a high melting point, good heat resistance, high electrical resistivity, and ultra-high oxidation resistance. It is mainly used as an additive for non-ferrous alloys and is an indispensable basic raw material for many high-tech industries.
