Ferroelectric ceramics for dielectric power conversion. Annual report, March 1, 1979-April 30, 1980

Description: Materials selected for study were those which could be expected to have useful Curie temperatures, resistivities, coercive fields, and Devonshire coefficients. Materials studied include PZT (lead-zirconia-titania system), Bi(Na,K)Ti/sub 2/O/sub 6/, rare earth titanoniobates, other tantalates and niobates, and thin films. Graphs are given for spontaneous polarization as a function of composition, temperature dependence of spontaneous polarization and coercive field for modified PSZT dielectrics,… more

ELECTRON MICROSCOPY STUDY OF THE FERROELECTRIC DOMAINS AND DOMAIN WALL STRUCTURE IN Pb.52Ti.48O3

Description: The crystallography of the domains and domain walls in PZT are studied using electron diffraction and transmission electron microscopy. Both 90{sup o} and 180{sup o} domains are observed and the 90{sup o} domains are shown to be deformation twins with displacement along <110> on {l_brace}110{r_brace}. The thickness of the 90{sup o} domain wall is determined to be {approx}< 100 {angstrom}. Leadon Zirconate Titanate (PZT) is a ferroelectric material at room temperature and it is used ext… more
