201731· In this high- temperature and pressure phase-diagram region, silica can metamorphose from quartz, the most stable form of SiO 2 at ambient conditions, to tridymite, cristobalite, coesite and stishovite. The first three polymorphs are well known for their low-temperature (α) and high-temperature (β) forms (Heaney, 1994 and Russell et al., 1994).

Datasheet Template
Cultured quartz is produced by placing small seeds of quartz mixed with an alka-line solution in an autoclave. This mixture is subjected to high heat (> 400°C) and high pressure (30,000 psi). This causes the quartz to dissolve and reform as thin slices of quartz. This pro-cess takes approximately 30-45 days.
