摘      要：Lead zirconate titanate(PZT)ceramics possess great potential for practical applications and thus improving their piezoelectric prop­erties is ***0.99−xSm0.01BaxZr0.53Ti0.47O3(PSBZT)ceramics with high Curie temperature and excellent piezoelectric properties were fabricated via a conventional solid-state method,and the effect of Ba2+doping on the structural,dielectric,piezoelectric and ferroelectric properties was studied in *** is shown that doping of Ba2+significantly enhanced the piezoelectric properties of PSZT,the maximum d33~533 pC/N and Tc~361°C at x=0.02 were ***,PSZT and PSBZT ceramics were used to prepare single element ultrasonic transducers,and their performance were compared and *** results demonstrate that the PSBZT ceramic-based transducer possesses better sensitivity and bandwidth than the PSZT ceramic-based transducer.
