Abstract

The textured (BiNa)0.5TiO3–BaTiO3 ceramic with a preferred 〈h00〉 orientation was fabricated by tape casting with the plate-like Bi2.5Na3.5Nb5O18 (BINN5) particles as template. Effects of processing parameters and the content of template on the microstructure and the texture fraction of NBT-based ceramics were investigated. The results show that the texture fraction increases with increasing sintering temperature and the increasing content of BINN5. The increased sintering temperature and BINN5 content result in the grain size and the grain shape changing from irregular to plate like. These factors were responsible for the increased degree of orientation. The texture fraction had a maximum value when the sintering temperature is 1225 °C and the optimal content of template is 20 wt.%.
