Hydrothermal Synthesis - an overview | ScienceDirect Topics

Hydrothermal method. The hydrothermal method is a simple, versatile and universal synthesis method that usually employs an alkaline-based solvent at moderate temperature and high pressure to produce TiO 2. The main chemical reaction occurs at a critical temperature and high pressure in a stainless-steel Teflon autoclave.
