Abstract
The dielectric constant and spontaneous polarization of fine-grained BaTiO/sub 3/ prepared from powder produced by metalloorganic decomposition technology were studied. The room-temperature dielectric constant of BaTiO/sub 3/ was found to increase sharply with increase in grain size, reach a maximum at about 0.4 mu m, and decrease with further increase in grain size. Spontaneous polarization continuously decreased with decrease in grain size. A model is proposed to explain the grain size dependence of the dielectric constant.<>
