Abstract The mechanisms of texture development were examined for BaTiO3 and a K,Na,LiNb,TaO3 solid solution made by the templated grain growth method, and compared with the mechanism in Bi0.5Na,K0.5TiO3. The dominant mechanism was different in each material; grain boundary migration in BaTiO3, solid state spreading in Bi0.5Na,K0.5TiO3, and abnormal grain growth in the K,Na,LiNb,TaO3 solid solution. The factor determining the dominant mechanism is the degree of smoothness of surface structure at an atomic level. View Full-Text
