Promising method of complex oxide phases synthesis by using low hydrated hydroxides of niobium and tantalum (Nb,Ta)O{sub x}(OH){sub 5-x}.mH{sub 2}O precursors of high reactivity and sorption ability was developed. Precursors, intermediate products of synthesis and target materials were studied by thermogravimetric analysis, infrared spectroscopy and X-ray diffraction. Sorption process of magnesium and lead cations by niobium low hydrated hydroxide from acetic solution allows obtaining PbMg{sub 1/3}Nb{sub 2/3}O{sub 3} complex perovskite without any secondary phase.
