Abstract

Lead magnesium niobate Pb(Mg1/3Nb2/3)03 was prepared by molten salt synthesis using 0.635Li2SO4-0.365Na,SO4 and the effects of PbO on the microstructure and dielectric properties of the resulting specimens have been investigated. At a temperature of 750°C, about 98% of the perovskite phase was synthesized. With the addition of excess PbO up to 3 mol%, the relative density and the dielectric constant for the specimens sintered at 900°C were about 97% and 15,000 at 1 kHz, respectively. Further additions of excess PbO resulted in lower densities and inferior dielectric constant, mainly due to the formation of a PbO rich phase in the grain boundaries.
