A comprehensive thermodynamic model of hydrothermal reactions has been developed to predict the optimum conditions for synthesizing perovskite ferroelectric compounds. The model indicates the ranges of reagent concentrations, pH and temperature for which the desired product can be synthesized with the highest possible yield. The synthesis conditions for the Sr-Ti system have been compared with those for the Ba-Ti system. The predictions have been experimentally verified. As a result, phase-pure SrTi03has been obtained using Sr(N03)2or Sr(0H)2.8H20 as sources of strontium and hydrous and anhydrous Ti02as a source of titanium.
