Abstract: By introducing polyethylene glycol (PEG) to the conventional simultaneously mixed oxide reaction route, the 0.65Pb(Mg1/3Nb2/3)-0. 35PbTiO3 (0.65PMN-0.35PT) powders and ceramics with pure perovskite phase have been successfully synthesized. It is found that PEG interacts with PbO oxide in a way favoring the formation of the desired perovskite phase. As a result, pyrochlore-free 0.65PMN-0.35PT powders are synthesized at a low temperature of 850°C. The ceramics sintered at 1000°C show uniform grains with the size ranging from 1 to 3 μm. The room temperature dielectric constant is 3440. The maximum dielectric constant is 16 220 at 1 kHz. This method can be applied to the synthesis of other Pb-containing and Bi-containing ferroelectric materials, especially the relaxor-type ferroelectrics in which the pyrochlore phase is difficult to eliminate.
