Resumen:
Mixed crystalline alpha zirconium-titanium phosphates with 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 phosphoricacid. Chemical analysis, X-ray diffraction, TEM-AEM, XPS and thermal analysis were used to characterized these materials. A broad rangr of ttanium-zirconium phosphate solids were found to form.
