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.
