Hydrothermal Method - an overview | ScienceDirect Topics

Hydrothermal synthesis can be defined as a method of synthesis of single crystals that depends on the solubility of minerals in hot water under high pressure. The crystal growth is performed in an apparatus consisting of a steel pressure vessel called an autoclave (see Figs. 6.16 and 6.17 ), in which a nutrient is supplied along with water.
