Low Temperature Sintering Behavior and Giant Dielectric Properties of CuO Doped (Ba_0.5Sr_0.5)TiO₃ Ceramics

摘要

The effects of CuO additions on the sintering temperature and dielectric properties of (Ba_0.5Sr_0.5)TiO₃ ceramic have been investigated by employing X-ray diffraction analysis, and dielectric properties measurements. In this research, 1-5 wt% CuO was added to the (Ba_0.5Sr_0.5)TiO₃ powders to reduce the sintering temperature. CuO-doped (Ba_0.5Sr_0.5)TiO₃ ceramics were sintered from 750 to 1350°C to confirm the sintering temperature with various dopants, respectively. It was found that the addition of CuO to (Ba_0.5Sr_0.5)TiO₃ could lower the sintering temperature from 1350 to 1150°C. Moreover giant dielectric permittivity was observed in the 5 wt% CuO doped (Ba_0.5Sr_0.5)TiO₃ ceramics.View full textDownload full textKeywordFerroelectrics, dielectric responseRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00150193.2012.677663
