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, in which a nutrient is supplied along with water.
Hydrothermal synthesis involves creating single crystals through a process dependent on minerals' solubility in hot water at high pressure. This method takes place inside a steel vessel called an autoclave, which includes a nutrient supply along with water.
