Low temperature characteristics of ionic conduction in (Bi_2O_3)_0.73(CaO)_0.27 ceramics were investigated by ac impedance analysis. In the 200 to 500℃ temperature range grain boundary effect was not separated in the impedance plane. The speciments with larger grain size exhibited higher electrical conductivity and lower activation energy than deternined to be 101 kJ/mol, which was very close to the reported value, 106 kJ/mol. At 300℃ and lower temperatures conductivity curve bent toward higher conductivity, as was reported in the some other ion conducrors. The conductivity showed aging effect at temperatures lower than 350℃, but conductivity decrease was not significant.
