Abstract
Piezoelectric properties in a Ba(Zr0.075Ti0.925)O3 single crystal were investigated with a consideration that its phase transition lies on room temperatures and the transition can affect piezoelectric properties. The poling treatments were carried with bias fields ranging 2.2 kV/cm∼11 kV/cm at room temperature. The crystal possesses the phase transition from orthorhombic to rhombohedral, lying on room temperature. At 37∘C, the crystal exhibited the excellent piezoelectric properties, a d31 coefficient of over 500 pC/N and a k31 coefficient of 0.38, being caused by the phase transition.
