| Popis: | In this study, we report the production of β˝-Al 2 O 3 solid electrolyte by using Seydisehir α-Al 2 O 3 . Alumina has to be low grain-sized to ensure α-β phase transformation. Therefore, grain refining process was applied to high grain sized Seydisehir alumina by jetmill grinding. Seydisehir alumina was calcined at 1200 0 C for 2 hours. After calcination, calcined Al 2 O 3 and Na 2 CO 3 were mixed during 2 hours in the mill. The samples were pressed and sintered to obtain β˝-Al 2 O 3 . β˝-Al 2 O 3 was obtained after sintering at 1550°C for 1 hour. Due to the formation of β˝-Al 2 O 3 , it is observed that dielectric properties increased. |
