Micron-sized powders of layered-structure compounds were prepared by solid-state reactions, and ceramic compacts densified by hot-forming methods. Materials included: Bi/sub 2/WO/sub 6/, Bi/sub 2/MoO/sub 6/ PbBi/sub 2/Nb/sub 2/O/sub 9/ and Bi/sub 4/Ti/sub 3/O/sub 12/; and ceramic microstructures were oriented by hot-pressing, hot-forging and hot-extension methods. Temperatures of 800-1100/sup 0/C were used, with pressures of 35 MPa. Grain orientation factors of 99% were determined by x-ray diffraction analyses. Anisotropy in electric properties were determined. Data are reported for the microstructure-dependent dielectric properties.
