摘要

Pure perovskite 0.68Pb [Mg_1/3(Nb_(1-x)Ta _x)_2/3]O₃-0.32PbTiO₃ (0.68PMNTa-0.32PT) ceramics were prepared by one-step calcination method using Mg(NO₃)₂ instead of MgO as starting chemical. The dielectric properties as a function of temperature and P-E and ε-E loops were investigated in this work. The T_m and T_c shift down for ∼13°C with Ta addition. The ε_m with Ta-doping is higher than that without doping. Both of the diffusion phase transition and frequency dispersion are weak, but the relaxor feature with Ta-doping is more apparent than that without doping. Both of the values of P_r and E_c decrease with Ta addition, and the values of remnant and maximum strain increase with Ta-doping.
