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
