Abstract
Perovskite Ba(Mg1/3Ta2/3)O-3 powders have been produced by hydrothermal synthesis at less than or equal to 200 degrees C. It was shown that the perovskite particles are irregular in shape and magnesium deficient, and that the excess magnesium was precipitated separately as the hydroxide. An improved method was developed and the resulting powder had a high proportion of rounded near-stoichiometric particles, although some irregular shaped;magnesium-deficient particles were also present. Thus, a link has been found between the stoichiometry and morphology of particles, which suggests that the mode of growth is affected strongly by particle stoichiometry.
