Abstract

Piezoelectric ceramics Pb_0.955La_0.03(Zn _2/3Nb_2/3)_0.3(Zr_xTi _1-x)_0.7O₃ with different Zr contents were fabricated by hot-pressing sintering process, and their piezoelectric constant d₃₃ at room temperature were obtained. d₃₃ value of 0.3PZN-0.7PZT ceramics with Zr 52% content fabricated by hot-pressing sintering process, can reach 740 pC/N. Resonance frequency f_r dielectric constants ε _r, electromechanical coupling factor K₃₁ and piezoelectric constants d₁ were measured as a function of temperatures between 10°C and 100°C. The above mentioned values were compared with those of Pb_0.955La_0.03(Zn _1/3Nb_2/3)_0.3Zr_0.37Ti _0.33O₃ fabricated by conventional sintering process. The results show that the temperature stability of piezoelectric ceramics fabricated by hot-pressing sintering process is better than that by conventional sintering process.
