| Popis: | The structural change of 0.6Pb(Zr1-x Ti x )O3-0.4Pb(Zn1/6Ni1/6Nb2/3)O3 (PZT x –PZNN) from rhombohedral to tetragonal is significantly dependent on the ratio of Ti/Zr. PZT0.570–PZNN ceramics exhibit the highest piezoelectric properties (d 33 = 661 pC/N, k p = 0.68, and e 33 T /e 0 = 3928) as a result of the MPB formation. However, the optimum sintering temperature of this composition is approximately 1200 °C, which restricts the use of pure, cheap metal electrodes in the fabrication of multilayer ceramic actuators. In this study, a low temperature sintering of PZT0.570–PZNN ceramics with the addition of CuO is reported. It is found that the addition of CuO can significantly reduce the sintering temperature to 900 °C. The piezoelectric properties of the 2 mol% CuO-added PZT0.570–PZNN sintered at 900 °C are d 33 = 602 pC/N, k p = 0.65, e 33 T /e 0 = 3570, and T C = 251 °C. |
