We synthesized the ferroelectric perovskite oxide LaCrO3 (LCO) using solid-state reaction method. Scanning electron microscope (SEM), energy x-ray dispersive (EDX) and X-ray diffraction (XRD) have been employed to study structural and chemical analysis of synthesized powder, respectively. Electrical admittance properties of the perovskite oxide sample was performed in wide range frequency (1Hz-10MHz) and temperature (-100 °C to +100 °C) using dielectric/impedance spectrometer. The results showed that the LCO has different activation energies and the calculated activation energies are of 0.175 eV and 0.220 eV from the Gdc vs. 1000/T and 0.152 eV and 0.197 eV from the fmin vs. 1000/T plots, respectively. The temperature-dependent exponent s showed that the overlapping large polaron tunneling (OLPT), quantum mechanical tunneling (QMT) and the correlated barrier hopping (CBH) conduction mechanism models can be suggested for the LCO compound.
