Bulk BaTiO 3 ceramics with 〈111〉‐texture have been prepared by the modified templated grain growth method, using platelike Ba 6 Ti 17 O 40 particles as templates, and the mechanism of texture development is examined. The Ba 6 Ti 17 O 40 particles induce the abnormal growth of BaTiO 3 grains, and a structure similarity between {001} of Ba 6 Ti 17 O 40 and {111} of BaTiO 3 gives 〈111〉‐texture to abnormally grown BaTiO 3 grains. Thus, the 〈111〉‐texture develops in the BaTiO 3 matrix. The use of platelike Ba 6 Ti 17 O 40 particles has been extended to a 0.65Pb(Mg 1/3 Nb 2/3 )O 3 –0.35PbTiO 3 matrix, but the matrix phase is decomposed by extensive chemical reactions between the matrix and template phases.
