Abstract
A citrate precursor method was employed to synthesize leadfree perovskite 05BaZr02Ti08O305Ba07Ca03TiO3 BZT05BCT crystallites Powders and gels were characterized by Xray diffraction Fourier transform infrared spectroscopy Raman spectra thermal analysis and transmission electron microscopy It was indicated that BZT05BCT transparent gel can be obtained via the chelation of citric acid with metal ions Gels transformed into crystalline powders with singlephase perovskite structure when heattreated above 650 °C significantly lower than that in a solidstate reaction method The primary particle size of the powders increased from 30 to 60 nm as the decomposition temperature was raised from 600 to 750 °CThis work was financially supported by the Fundamental Research Funds for the Central Universities and by the National Natural Science Foundation of China 50972035 and a Program for New Century Excellent Talents in University State Education Ministry NCET080766
