DESCRIPTION
silicon metal is also called industrial silicon or crystalline silicon. It is silver-gray with a metallic sheen, and when processed into a powder, the color is dark gray. It has a high melting point, good heat resistance and high resistivity. It is commonly used in the electronics, metallurgy and chemical industries. It is an indispensable raw material for the high-tech industry.
