The effectiveness of nonhydrolytic Sol-Gel process to the synthesis of homogeneous bicomponent gels has been studied in the case of aluminium titanate and zirconium titanate. The direct crystallization of Al2TiO5 and ZrTiO4 at low temperature without the intermediate formation of TiO2 or Al2O3 in the former case and TiO2 or ZrO2 in the latter indicates that homogeneous bicomponent gels have been formed by this route.
