Large electrostrictive properties in lead-free BaTiO3–ZnSnO3 solid solutions

A new lead-free perovskite piezoelectric solid solution (1−x)BaTiO3–xZnSnO3 (BT–xZS) was designed and fabricated using the traditional solid-state reaction method. The introduction of ZnSnO3 was found to shift the high-temperature cubic phase of BaTiO3 to lower temperatures. At room temperature large electrostrictive coefficient up to 0.0452 m4 C−2 was obtained in BT–0.10ZS ceramic, which is much larger than the traditional electrostrictive material Pb(Mg1/3Nb2/3)O3 and recently reported lead-free electrostrictive systems. The large electrostrictive response of BT–xZS ceramics makes them quite potential to be applied to new solid-state actuators.
