Abstract
The thermal properties (TGA, DTA) and AC electrical conductivity of pure In2O3 and ZrO2 doped In2O3 have been studied. The dopants ratio were 1, 3, 5, 8 and 10 mol % of ZrO2. The AC conductivity as a function of temperature was measured in the temperature range 298- 753 K at a frequency 20 KHz. The plots of log σ(Ω-1 cm-1) vs. 1/T (K-1) showed that all curves have three parts and the activation energies for conduction were calculated.
