摘要
Powder materials having the composition Pb0.88Ba0.12(Zn1/3Nb2/3)0.30(Mg1/3Nb2/3)0.50Ti0.20O3 were prepared by a two-step calcination method. All the constituent oxides, except for PbO, were precalcined, and then the resulting mixtures were postcalcined with PbO to obtain powders having the desired composition. A series of experimental studies of the powder and the ceramic showed that samples fabricated by the present method had better properties in terms of perovskite phase purity, sinterability, breakdown voltage and dielectric constant, compared to those prepared by the conventional method using one-step calcination.
