Measurements of mechanical strains on the lead titanate zirconate series were made during poling and the results were interpreted in terms of domain alignment. Electron micrographs were made before and after poling. Thermal expansion was measured and interpreted in terms of domain reorientation snd crystal distortion. Coercive force and remanent polarization were measured over wide compositional and temperature ranges. Permittivity was measured ae a function of mechanical stress. The ferroelectric properties of lithium trihydrogen selenite were investigated, and preliminary piezoelectric and elastic measurements were made. Elastic, dielectric, and piezoelectric constants of hexagonal (wurtzite) cadmium sulfide were measured. (For preceding period see SC- 4306.) (auth)
