The first step in preparing a target material using this synthesis strategy is to determine the initial concentrations of the precursors based on the stoichiometric relationship. Knowing the phase diagram of the target system, in principle, it is possible to determine the initial conditions for performing experiments under hydro(solvo)thermal conditions. These chemically intuitive aspects are key to obtaining better results in the use of hydrothermal reactions. In addition, controlling thermodynamic factors (pressure and temperature) facilitates diffusion by reducing viscosity , thereby promoting the solubility of the reagents and affecting the growth of the crystal. After obtaining and confirming the initial results, the chemical parameters of the process are optimized for the synthesis of the target advanced material.
