Abstract
Ferroelectric samples of the 0.65Pb$(Mg_{1/3}Ta_{2/3})O_3-0.35PbTiO_3$ modified with $Ag_2O$ were prepared by sintering at $1200^{\circ}C$ for 4 h. The fractured surface of sintered pellets were examined by scanning electron microscopy(SEM). The dielectric constant, loss, and pyroelectric coefficient of the ceramics samples were determined. The dielectric and pyroelectric properties could be improved with the addition of small amount of $Ag_2O$ up to 0.2 mol%. The dielectric and pyroelectirc peak temperatures are continuously shifted to lower temperature with addition of small amounts of $Ag_2O$.
