has been prepared by citrate gel pyrolysis using peroxo titanium complex as one of the reactants, and ethylene glycol as gelating reagent. The compound was analyzed by powder XRD and infrared methods. It is found to crystallize in rhombohedral lattice with space group
. The infrared spectra of samples prepared at different temperatures consist of mainly bands due to phosphate (PO

) group. The morphological characterization was carried out by transmission electron microscopy. The crystallite size was estimated from the line width of intense powder diffraction line using Scherrer's formula and TEM images.
