Abstract  

Ba3Ca1.18Nb1.82O9-δ powders with different particle sizes were synthesized by high temperature sintering (1400 ℃/10 h) of the mixed powders of BaCO3, CaCO3 and Nb2O5 milled for different times. Laser paticle size analysis, DSC--TG and SEM results show that the proper milling time can make particle refine, decrease the synthesis temperature, and increase the density of sample. EIS result shows that the temperature dependences of total conductivities of the sintered samples prepared by 6 and 10 h milling conform to the Arrhenius equation in the measured temperature range of 300---800 ℃, and the activation energies are 0.84 and 0.68 eV, respectively. Raising the density of Ba3Ca1.18Nb1.82O9-δ sample is an effective way to decrease the activity energy and increase the total conductivity at low and intermediate temperatures (300---600 ℃).
