Silica sand, the substance used to derive pure silicon, is made of quartz, which is the most common form of silica found in nature. Crystalline silica exists in seven different forms. The three major forms, quartz, cristobalite and tridymite, are stable at different temperatures. Within the three major forms are subdivisions. Crystalline silica is ubiquitous, being in rocks from every geologic ...
