Abstract

AR grade Li₂CO₃ and MnCO₃ have been mixed in the mole ratios 0.5 : 1 (sample 1) and 0.7 : 1 (sample 2) and synthesized at 800Â°C for four hours. On the basis of XRD analysis, the former is determined as a single phase spinel and the later shows the presence of Li₂MnO₃. The cation distribution is different for the two samples. The electrical conductivity and dipolar relaxation are larger for the later sample. It has been concluded that the cation distribution as well as presence of additional phase is responsible for the changes in the properties.
