The mechanism of the preparation of 0.5Pb(Mg_1/2W_1/2)O₃-0.5PbTiO₃(PMW-PT) powder by the semichemical method was studied. The precursors were prepared by addition of an aqueous Mg(Ac)₂ solution into the alcohol slurry of PbO, WO₃ and TiO₂ instead of solid MgO commonly used. The TG-DTG-DSC analyses of the precursors and XRD analyses of the powders obtained at different calcination temperatures show that the mechanism of this method is different from that of the conventional mixed oxide method. The aqueous Mg(Ac)₂ solution reacts with PbO to form Pb(Ac)₂·Pb(OH)₂·H₂O, Pb(Ac)₂·2PbO·H₂O and Mg(OH)₂, which decompose to form nascent PbO and MgO, significantly improving the reactivity and dispersion of PbO and MgO. The method requires much lower temperature for the formation of the perofskite PMW-PT phase. At a calcination temperature of 850℃, PMW-PT powder with 99% perofskite phase could be obtained.
