Abstract:

The phase structure, microstructure and electrical properties of (1-x)Pb (Zr_yTi_1-y)O₃-xSm(Fe³⁺_0.5, Nb⁵⁺_0.5)O₃ (PZT–SFN) (with x = 2 %, 41%≤ y ≤57 %) piezoelectric ceramics were prepared by the conventional solid state method, and effects of SFN and the Zr/Ti ratio content on the piezoelectric properties of PZT ceramics were mainly investigated. A stable solid solution has been formed between PZT and SFN, and a morphotropic phase boundary of PZT–SFN ceramics is identified in the range of 51% ≤ y ≤55 %. The Curie temperature of PZT–SFN ceramics decreases with increasing at Zr/Ti ratio content. A higher ε_r value and a lower tanδ value are demonstrated for the PZT–SFN ceramics with y = 53 %. The PZT–SFN ceramics with y = 53 % has an enhanced electrical behavior of k_p ~ 61.2 %, Q_m ~ 104, ε_r ~ 566, tanδ ~ 2.02 % and T_C ~ 370 ^OC. As a result, PZT–SFN ceramics are promising candidate materials for the field of lead piezoelectric materials and piezoelectric device.
