Abstract

Abstract Highly conductive and stable β″-Al2O3 electrolyte powder is achieved via the solid-state reaction technique when sintered at 1200 °C, 1250 °C, 1300 °C, 1350 °C, and 1400 °C temperature, correspondingly. The findings show that the ionic conductivity has improved slightly from 1200 °C to 1400 °C. As the sintering temperature is increased, the EIS curve shows a short curve of resistance. A maximum ionic conductivity of 7.07 × 10−4 S cm−2 is achieved at 1400 °C (1800 Ω). This is caused by the large β″ contents in Al2O3, as inspected by the X-ray diffraction results. Furthermore, the morphology of Al2O3 shows less porosity and denser particles within the powder.
