Abstract

The mechanism for texture development in bismuth layer-structured ferroelectrics prepared by the templated grain growth method was examined using template and matrix grains with different chemical compositions. The template particles used were platelike Bi4Ti3O12 and Ba6Ti17O40 for SrBi4Ti4O15-matrix composites and platelike Ba6Ti17O40 and Sr3Ti2O7 for BaBi4Ti4O15-matrix. The 〈001〉-texture developed in all composites examined. The origins of texture development were the growth of matrix grains to be platelike and the formation of face-to-face contact between the template and matrix grains and also between matrix grains.
