| Abstract: | Pb(Mn_ 1/3Sb_ 2/3)_x(Zn_ 1/3Nb_ 2/3)_y(Zr,Ti)_zO_3 piezoelectric ceramics were fabricated.The effects of sintering temperature and heat-treatment time on properties were discussed,the optimum preparation technology parameters were obtained.In this case,the ceramics have the highest electromechanical coupling coefficients and mechanical quality factor and the least dielectric loss.It revealed that the PMZN piezoceramics material can be utilized for high-power ultrasound transducer. |
