Novel high-temperature ferroelectric single crystals 0.38Bi(Mg1/2Ti1/2)O-3-0.62PbTiO(3) with good and temperature-stable piezoelectric properties

摘要

Novel ferroelectric single crystals 0.38Bi(Mg1/2Ti1/2)O-3-0.62PbTiO(3) have been successfully grown by a flux method. The T-c and d(33) are 520 degrees C and 208 pC N-1, respectively. Good temperature stability, together with good piezoelectric properties and high Tc make the single crystals promising novel piezoelectric materials for high-temperature, high-performance actuators and transducers.
