Description :
The electrical characterisation of Alkali Oxide of Transition Metal, Li2ZrO3 is presented in this study. In-situ impedance spectroscopy measurements were carried out in different partial pressures of oxygen embedded in dry Argon in temperature range 300-500oC. Impedance analysis was done by formulating equivalent RC circuits. Wagner's approach was employed to the material in pallet form for DC measurements, where blocking electrodes were kept under comparable atmospheric conditions.
A mixed conducting window best suited for the sensor's open reference electrode functioning at roughly 300oC has been identified using electronic and ionic conductivities and transport numbers.
