Abstract :
[(Bi0.5Na0.5)TiO3]0.92–[BaTiO3]0.08 lead free piezoelectric materials were prepared by the pyrosol method. The as-obtained powder shows spherical grains of various sizes, composed of crystallites of about 10 nm. NBT–BT0.08 ceramic obtained at 700 °C show rhombohedral NBT as the main phase and traces of hexagonal Bi2O3 as secondary phase. The ceramics prepared from this powder and sintered at 1000 and 1100 °C are single phase with good dielectric and ferroelectric properties.
