Abstract

Bu çalışmada
hidrotermal sentez yöntemi kullanılarak PEG-400 destekli α-alumina sentezi başarılı
şekilde gerçekleştirildi. Yapı düzenleyici ajan olarak kullanılan PEG-400’un
parçacık boyutuna etkileri araştırıldı. Sentezlenen tozların yapısal
karakterizasyonu XRD, Raman ve FTIR yöntemleri kullanılarak gerçekleştirildi.
Termal özelliklerin araştırılmasında TGA yöntemi kullanıldı. Morfolojik özellikler
ise SEM yöntemi kullanılarak araştırıldı. Çalışmanın sonuçları yapı düzenleyici
ajan kullanılmadan gerçekleştirilen deneyle karşılaştırıldığında daha küçük
boyutlarda saf α-Al₂O₃ elde edildiğini göstermektedir.

Keywords
