Texture development in piezoelectric ceramics by templated grain growth using heterotemplates

The mechanisms of texture development were examined in the 〈0 0 1〉-textured bismuth layer-structured ferroelectrics (BLSF) prepared by the templated grain growth (TGG) method using BLSF templates with the composition different from that of the matrix. The formation and growth of layers of matrix grains on the templates were main mechanism for the texture development. Another mechanism of texture development was the formation of face-to-face contact between platelike template grains and matrix grains grown to be platelike.
