The dielectric and piezoelectric properties of silver doped $Pb(Zr,Ti)O_3-Pb(Mn,W,Sb,Nb)O_3$ ceramics was examined. By varying the contents of silver(0.0, 0.4, 1.0 mol%), the effect of doped silver on PZT-PMWSN thin film was investigated at various sintering temperature(900, 1000, $1100^{\circ}C$). As increasing silver contents, the relative dielectric constant is increased and sinterbility is enhanced. At the specimen with 0.4 mol% Ag and sintered at $1100^{\circ}C$, electromechanical coupling factor(kp), mechanical quality factor(Qm), dielectric constant(${\varepsilon}r$) and dielectric loss were 0.502, 811, 991, 0.006, respectively. The results show that the PZT-PMWSN/Ag composites have enhanced piezoelectic and dielectric properties and processing condition is improved.

The dielectric and piezoelectric properties of silver added 0.96 Pb(Z $r_{0.52}$ $Ti_{0.48}$) $O_3$-0.04 Pb(Mn,W,Sb,Nb)$_3$ ceramics were examined. By varying the contents of silver(0.0, 0.4, 1.0 mol%), the effect of silver addition on PZT-PMWSN ceramics was investigated at various sintering temperature(900, 1000, 1100 $^{\circ}C$). As increasing silver contents, the relative dielectric constant was increased and sinterability was enhanced. At the specimen with 0.4 mol% Ag and sintered at 1000 $^{\circ}C$, electromechanical coupling factor( $k_{p}$), mechanical quality factor( $Q_{m}$), dielectric constant($\varepsilon$$_{r}$) and dielectric loss were 0.502, 811, 991, 0.006, respectively. The results showed that the PZT-PMWSN/Ag composites have enhanced piezoelectic and dielectric properties and sintering temperature was lowered.red.
