摘要

Structural, dielectric, ferroelectric and piezoelectric properties of lead magnesium niobate-lead titanate, PMN-PT (66:34), prepared at different sintering temperatures (1150-1250℃) are discussed for actuator applications. System sintered at 1200 and 1250℃ showed better perovskite phase stabilization and higher values of dielectric constant (ε_r). Remnant polarization (P_r) was found to be higher (45 μC/cm~2) for the system sintered at 1250℃. The piezoelectric coefficients, d_(33), d_(31), d_h and strain induced in the system by a large electric field were found to be sintering temperature dependent. Hysteresis free strain behavior of the system sintered at 1200℃ showed the suitability of this material for actuator applications.
