17.08.2015The raw material for silicon, silica, is the most abundant mineral on Earth, including quartz, chalcedony, white sand, and numerous noncrystalline forms. The first step in silicon production is to reduce silica with coke to generate metallurgical-grade silicon, SiO2 + C Si + CO2. (9.88) The silicon thus produced is typically 98% pure.
