Texture Development in Na_(1/2)Bi_(1/2)TiO_3BaTiO_3 Ceramics by Reactive-Templated Grain Growth

摘要

High <001>-textured Na_(1/2)Bi_(1/2)TiO_3-BaTiO_3 (6mol%BaTiO_3) ceramics were fabricated by reactive-templated grain growth (RTGG), using plate-like Bi_4Ti_3O_(14) particles prepared by a molten salt method as the templates. The effect of template concentration on the texture development and microstructure evolution was studied, and the mechanisms of grain orientation and densification were also discussed. The design of Bi element reaction has important impact on the texture development.
