PMN from water suspension by one step synthesis

Lead magnesium niobate PbMg1/3Nb2/3 (PMN) was synthesised from water suspension at control pH. Lead and niobium oxide and different magnesium raw material has been used for synthesis. High alkaline media was used during homogenisation of starting material. After homogenisation step powder was separated, dried and fired at temperature from 700 - 00 degrees Celsius. Pure lead magnesium niobate - PMN without undesirable pyrochlore phase was present in the syntehsised powder. Synthesis from suspension is one-step synthesis compare to the classic two-step columbite synthesis method from oxide precursors.
