Silicon - Mine Engineer.Com
Silica dioxide is a mineral. This is quartz or common sand's basic constituent. Silicon is produced by heating sand (SiO2) with carbon to temperatures around 2200°C. At room temperatures, silicon exists in two forms, amorphous and crystalline. Amorphous appears as a brown powder while crystalline silicon has a metallic luster and a grayish color.
