Abstract

Cubic-shaped Bi_0.5Na_0.5TiO₃ (BNT) and Bi_0.5K_0.5TiO₃ (BKT) fine particles with narrow size distribution were directly prepared as a single phase from a suspension of TiO₂ anatase nanoparticles mixed with Bi(OH)₃ in aqueous alkaline metal hydroxides solutions by highly condensed hydrothermal method at 200-250°C for several hours. It was investigated that the effect of particle mean size on the piezoelectric properties of thus obtained BNT and BKT fine particles.
