Abstract

Bu deneysel çalışmada, spinel
seramiklerin önemli bir türü olan kalsiyum aluminat (CaAl₂O₄)
nanopartiküllerin basit, hızlı ve etkili bir sentez tekniği olan mikrodalga destekli
yakma metoduyla sentezlenebilirliği ve karakterizasyonu araştırılmıştır. Bu
amaçla yakıt olarak üre kullanılarak CaAl₂O₄
nanopartiküller mikrodalga destekli yakma metoduyla sentezlenmiştir. Elde
edilen ürünler TGA, XRD, FT-IR, SEM ve TEM teknikleri ile kapsamlı bir şekilde
analiz edilmiştir.  Bu üründe yapılan XRD
ve FT-IR analizleri uygulanan mikrodalga etkisinin ürünlerin tam dönüşümünde
tek başına yeterli olmadığı belirlenmiştir. Buna göre,  elde edilen nanopartiküllerin yapısal ve
morfolojik özelliklerini iyileştirmek ve ürüne dönüşüm oranını arttırmak için
300°C ile 1000°C derece arasında değişen sıcaklıklarda ısıl işleme
tabi tutulmuştur. 800°C ve üzerindeki sıcaklıklarda uygulanan ısıl işlem
sonrasında elde edilen partiküllerin tamamen kalsiyum aluminat nanopartiküllere
dönüştükleri belirlenmiştir.
