| Abstract: | In the paper the composition PbO SrO BaO Nb 2O 5(PSBN) system feroelectric ceramic is prepared by general electronic ceramic processing and dielectric properties relating to sintering temperature were studied. The XRD analyses indicate that the major phase of the system is Pb 0.7 Ba 0.3 Nb 2O 6(PBN), Sr 0.5 Ba 0.5 Nb 2O 6(SBN), and Ba 0.27 Sr 0.75 Nb 2O 5.78 (BSN). We consider the system as a three component solid solution. The ratio of PBN, SBN, and BSN is changed by their sintering temperature. It effects the change in dielectric properties of PSBN system whose dielectric constant is increased and curie temperature is moved to negative temperautre when the sintering temperature is increased. |
