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.d.d.d.
