| Popis: | The present study is an investigation of the effects of Sm2O3 doping on properties near morphotropic phase boundary (MPB) of nickel niobium ternary system lead zirconate titanate (PNN–PZT) ceramics. Pb(Ni1/3Nb2/3)0.5 (Zr0.3Ti0.7)0.5O3 (0.5PNN–0.5PZT + xSm) piezoelectric ceramics were prepared by a traditional two-step solid-state reaction method. The specimens exhibit the homogeneous perovskite structure without the secondary phase. When x = 0.6 wt% and x = 0.8 wt%, their diffraction peaks are the most obvious, they may have the best P–T MPB composition. The samples exhibit the P–T MPB composition have a good properties, which is in accord with the electric properties variation and the crystalline grain variation well. When x = 0.6 wt%, the ceramics exhibited electric properties: d33 = 688 pC/N, kp = 0.579, er = 6260, tanδ = 0.0207. It shows that the P–T MPB composition have relationships with the electric properties variation and the crystalline grain variation to some extent. |
