Resumen:
Mixed crystalline alpha zirconium- titanium phosphates with variable zirconium to titanium molar ratios have been prepared by the sol-gel process, using as precursors Zr[O(CH2)2CH3]4 and Ti[OCH(CH3)2]4 mixed at differents ratios which are hydrolized with phosphoric acid. Chemical analysis, X-ray diffraction, TEM-AEM, XPS and thermal analysis were used to characterize these materials. A broad range of titanium-zirconium phosphates solid solutions were found to form.
