Brief Introduction Of Silicon Metal

Metallic silicon, also known as industrial silicon or crystalline silicon, is a grayish, lustrous semi-metal with high melting and boiling points. It is primarily produced by reducing silica (SiO₂) with carbon in an electric arc furnace. With a typical purity ranging from 98% to 99.5%, metallic silicon is a key raw material in various industries.
