Abstract

The synthesis of composite titanium phosphate has been performed in one of the incisions of the TiO2-SiO2-H2SO4-H3PO4-H2O system with fixed amounts of H3PO4 and SiO2 with respect to TiO2. The composition of the precursors and the products of their thermolysis was determineded using IR spectroscopy, X-ray phase analysis, TGA analysis, and the BET method. It has been demonstrated that the concentration of titanium (IV) in the initial solution plays a crucial role during the formation of the structure and phase composition of the precipitates. The obtained data may provide a basis on which the directed synthesis of the product with the desired ion-exchange properties could be carried out.
