Cubic-shaped Bi0.5Na0.5TiO3 (BNT) and Bi0.5K0.5TiO3 (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.
