Effect of CuO addition on piezoelectric properties of 0.05Pb(Al 0.5Nb0.5)O3-0.95Pb(Zr0.52Ti 0.48)O3+0.7 wt.% Nb2O5 + 0.5 wt.% MnO2 (PAN-PZT) ceramics was studied to decrease the sintering temperature below 900°C for LTCC. The PAN-PZT ceramics sintered at 1200°C had piezoelectric properties of d33 = 340 pC/N, k p = 61.6%, Qm = 1,725, and density of 7.5 g/cm 3. The addition of CuO significantly decreased the sintering temperature due to the formation of liquid phase containing a binary combination of PbO and CuO in grain boundary. Piezoelectric properties of d33 = 361 pC/N, kp = 57%, Qm = 145, and density of 7.8 g/cm 3 were achieved at sintering temperature of 900°C. The CuO doped PAN-PZT ceramics show high density and d33 at low sintering temperature though its electromechanical quality factor abruptly decreases due to the CuO additive effect.
