Abstract

In this study, the dielectric, structural and electrical properties of Pb(ZnS11/3TNbS12/3T)OS13T-BaTiOS13T-PbTiOS13T system ceramics were investigated with respect to the variation of YS12TOS13T addition amount. As the YS12TOS13T addition amount is increased, the resistivity at 100$^{\circ}C$ and the resonant/antiresonant frequencies and the frequency constant are slowly increased, and the grain growth is restrained until 0.4 wt% YS12TOS13T addition amount but continuously increased with the addition amount more than 0.4 wt% YS12TOS13T. As the YS12TOS13T addition amount is increased, the density, the diffuseness of dielectric constant and the induced polarization are increased until 0.4 wt% YS12TOS13T addition.
