A series of Ba1－xSrxTiO3 (BST) and BaZrxTi1－xO3 (BZT) solid solutions have been synthesized through the homogeneous phase precipitation route at low temperature (90 ℃) under low pH (8～9) in a short time (3～3.5 h). Structure, composition and morphology of those solid solutions were studied respectively by XRD, chemical analysis, SEM and AFM methods. The results showed that the cell parameters of them were linearly related with the composition of them, which was in accord with Vegard's law, and the powders of them had mutual miscibility, spherical shape, uniform distribution and precision component. The role of the compound mineralizer to make the reaction system form a homogeneous phase and release hydroxyl, and the mechanism of the aggregation growth of the BST and BZT particles in solutions with dispersants, were discussed briefly in this paper.
