Abstract

ZnO-added 0.41PNN-0.36PT-0.23PZ ceramics cannot be sintered below 950°C. However, when CuO is added, the liquid phase forms and specimens can be sintered even at 850°C. The dielectric constant (ε₃ ^T/ε₀), piezoelectric constant (d₃₃) and electromechanical coupling factor (k_p) increase with the addition of CuO and this is due to the enhancement of the density of the specimens. When CuO is added to 0.41PNN-0.36PT-0.23PZ ceramics, improvements of density, ε₃^T/ε₀, d₃₃ and k _p are also observed. However, the d₃₃ and k_p values of the CuO-added 0.41PNN-0.36PT-0.23PZ ceramics are less than those of the CuO- and ZnO-added specimens. Therefore, ZnO is effective in improving the piezoelectric properties of 0.41PNN-0.36PT-0.23PZ ceramics. Good dielectric and piezoelectric properties of d₃₃=575(pC/N), k_p=0.55 and ε₃^T/ε₀= 3900 are obtained for 0.41PNN-0.36PT-0.23PZ+3.0mol% ZnO with 1 mol% CuO sintered at 900°C for 2 h.
