Abstract

The effects of pre-sintering conditions were investigated on the final density and texture of piezoelectric Bi<SUB>0.5</SUB>(Na, K)<SUB>0.5</SUB>TiO<SUB>3</SUB> (BNKT) ceramics prepared by the reactive templated grain growth (RTGG) method. Bi<SUB>4</SUB>Ti<SUB>3</SUB>O<SUB>12</SUB> (BiT) platelets were used as a reactive template for the fabrication of BNKT with a preferred <100> orientation. The application of cold isostatic pressing (CIP) after the in-situ formation of regular perovskite-type BNKT was effective to increase green density before sintering and thus to increase the final density. The CIP treatment after the completion of in-situ conversion from layered perovskite into regular perovskite, however, resulted in sintered ceramics with the lower degree of orientation. The CIP treatment after the partial in-situ formation of perovskite phase produced both dense and highly textured BNKT ceramics.
