Abstract

The crystallization behavior of amorphous aluminum phosphate (AlPO4) has been studied by X-ray diffraction as a function of the treatment temperature (500–1150°C) in the presence of small amounts of titania (TiO2) anchored onto its surface. The compound, which like silica can exist in several possible crystalline modifications depending on the treatment temperature, is found to grow in the presence of TiO2 exclusively in a single phase in the entire range of temperatures studied. The phase has been shown to have the tridymite structure belonging to the orthorhombic system with cell parameters a = 9.638 ± 0.0019, b = 8.664 ± 0.0017, and c = 18.280 ± 0036Å.
