Development of texture in Bi_(0.5)Na_(0.5)TiO_3 prepared by reactive-templated grain growth process

摘要

The effect of sodium concentration on texture development in Bi_(0.5)Na_(0.5)TiO_3 [BNT] bulk ceramics was examined. The (100)-textured specimens were prepared by the reactive-template grain growth process using platelike Bi_4Ti_3O_(12) particles. Texture did not extensively develop in stoichiometric and Na-deficient BNT, but excess Na promoted extensive texture development together with densification. The role of excess Na was discussed based on the formation of a liquid phase.
