DESCRIPTION
The Silicon Metal is dark gray with metallic luster and features high melting point, good heat resistance, high resistivity as well as high oxidation resistance. In addition, industrial silicon is also used as an alloying agent for silicon steel, and as a deoxidizer for smelting special types of steel and non-ferrous alloys.
