Quartz is one of the most common minerals in the Earth's crust. Quartz is a hard, crystalline mineral composed of silica. As a mineral name, Quartz refers to a specific chemical compound (silicon dioxide, or silica, SiO2), having a specific crystalline form (hexagonal). It is found in all forms of rock: igneous, metamorphic and sedimentary.

polymorph of silica. At 573°C, α-quartz is transformed into β-quartz, generally similar in structure but with less distortion. This thermal transformation preserves the optical activity of quartz. Heating quartz to 867°C leads to the transformation of β-quartz into β-tridymite, involving the breaking of Si−O bonds to allow the oxygen
