Abstract

The effect of W⁶⁺ doped on lattice structure and piezoelectric properties of 0.2PZN-0.8PZT ceramics was investigated. The results show that the pure perovskite phase form in ceramics. The lattice constant is decreasing with increasing W⁶⁺ additive, also the ratio of c/a is decreasing with the addition of tungsten, which should be attributed to replacing B-section ions such as Zn²⁺, Nb⁵⁺, Ti⁴⁺ and Zr⁴⁺ by W⁶⁺. The additions of tungsten will increase dielectric constant e and mechanical quality factor Q_m, and decrease coercive electric field E_c, spontaneous polarization P_s, the electromechanical coupling factor K_p and piezoelectric constant d₃₃. The composition with 1.0% (mass fraction) of WO₃ addition on 0.2PZN-0.8PZT ceramics has the excellent piezoelectric properties, d₃₃ is 314pC/N, K_p is 0. 62 with the high Q_m amounted to 1178, which can meet the needs of high power piezoelectric devices.
