Includes bibliographical references. "The dependence of the electromechanical properties of unmodified lead zirconate-titanate ceramics on the grain size of the ceramic has been determined for materials with compositions on both sides of the rhombohedral/tetragonal boundary. High-density ceramics with average grain diameters from about 1.5μm to 8μm were examined. It was found that the dielectric constant before poling, and the dielectric and mechanical losses all decreased with increasing grain size. The coercive field was found to be largely independent of grain size in the range examined"--Abstract, p. xli. gccst Ceramics Weston, T. B. Canada. Natural Resources Canada. Canada.
