dc.description.abstractBismuth potassium titanate - strontium titanate (1-x)Bi<inf>0.5</inf>K <inf>0.5</inf>TiO<inf>3</inf>-(x)SrTiO<inf>3</inf> (BKT-ST) lead-free ceramics when x = 0-0.20 were synthesized by the solid state reaction method with normal sintering. The ferroelectric phase transition was studied by X-ray diffraction (XRD). All compositions showed a single phase perovskite structure with tetragonal symmetry at room temperature and the phase structure transformed from ferroelectric tetragonal - paraelectric cubic in the range of x ≥ 0.10. Dielectric study revealed that the dielectric relaxor behavior was induced with increasing ST and transition temperature (T<inf>m</inf> ε<inf>r max</inf>) of ST-doped BKT had a tendency to decrease with increasing ST. The Bi <inf>0.5</inf>K<inf>0.5</inf>TiO<inf>3</inf>-SrTiO<inf>3</inf> system was expected to be a new and promising candidate for lead-free capacitors. © (2011) Trans Tech Publications.
