【 摘 要 】

In this study, we report the production of β˝-Al₂O₃ solid electrolyte by using Seydişehir α-Al₂O₃. Alumina has to be low grain-sized to ensure α-β phase transformation. Therefore, grain refining process was applied to high grain sized Seydişehir alumina by jetmill grinding. Seydişehir alumina was calcined at 1200 ⁰C for 2 hours. After calcination, calcined Al₂O₃ and Na₂CO₃ were mixed during 2 hours in the mill. The samples were pressed and sintered to obtain β˝-Al₂O₃. β˝-Al₂O₃ was obtained after sintering at 1550°C for 1 hour. Due to the formation of β˝-Al₂O₃, it is observed that dielectric properties increased.
