The average crystallite size of the

The value of activation BMS265246 (Ea) of conductivity was calculated using Arrhenius equation:σT=A·exp[-Ea/RT]σT=A·exp[-Ea/RT]where σ is ionic conductivity (S cm−1), T is absolute temperature (K), R is gas constant 8.314 J K−1 mol−1, and Ea is activation energy (J mol−1).
