Crystallographic Texture Development in Bismuth Sodium Titanate Prepared by Reactive‐Templated Grain Growth Method

Abstract

Bi 0.5 Na 0.5 TiO 3 (BNT) and 0.94Bi 0.5 Na 0.5 TiO 3 ·0.06BaTiO 3 (BNT–BT) bulk ceramics with extensive 〈100〉 texture were prepared by the reactive‐templated grain growth method, using platelike Bi 4 Ti 3 O 12 (BIT) particles as templates for BNT. Calcined compacts were composed of matrix grains with random orientation and 〈100〉‐oriented grains transformed from aligned BIT particles, and the texture developed by the growth of oriented grains during sintering. Ceramics with extensive texture were obtained by using the starting mixture containing the maximum concentration of platelike BIT to form the maximum volume fraction of oriented grains.
