Abstract
The effects of Ag2O addition on the dielectric and piezoelectric properties of 0.96Pb(Zr,Ti)O3–0.04Pb(Mn,W,Sb,Nb)O3 (PZT–PMWSN) ceramics and thin films deposited on a Pt∕Ti∕SiO2∕Si substrate by pulsed laser deposition have been investigated. By varying the contents of silver from 0∼3mol.%, the effect of Ag2O addition on PZT–PMWSN ceramics and thin film was systematically observed. No reaction between silver and PZT is observed in X-ray diffraction analysis. Enhanced sinterability of PZT–PMWSN ceramics with Ag2O addition increased the electromechanical quality factor (kp) and mechanical quality factor (Qm). As silver content increased, it was observed that the relative dielectric constant (ϵr) increased because of increasing effective dielectric field in the dielectric phase.
