A technique involving high pressures and temperatures over a prolonged time in order to artificially synthesis crystals. The aim is to simulate conditions found in the earth’s crust and as such quartz and other gem stones, for example, have been grown. Hydrothermal synthesis uses water and more recently Solvothermal synthesis employs other solvents with the aim to …
