Hydrothermal Synthesis

Definition

Hydrothermal synthesis is a solution-based synthesis technique that involves the reaction of materials in a solvent at high temperatures and pressures, leading to the formation of crystalline materials. This method utilizes the unique properties of water under these conditions, such as its ability to dissolve a wide range of substances and facilitate reactions that may not occur under normal atmospheric conditions. Hydrothermal synthesis is particularly useful for producing nanostructured materials and improving the properties of solid-state batteries.
