Abstract

In
this study, we report the sinterability of Seydişehir α-Al2O3 by
coating TiO2 colloidal
particles by sol-gel method. In
this context, efforts have been made to decrease the amount of impurities with
washing process, to stabilize transformation with calcination and to reduce
grain size by jet-mill grinding. It is aimed to increase the density of Al2O3
by coating TiO2 by sol-gel method. The ceramic powders were
dry-pressed, they were sintered at 15800C for different hours(1h, 3h
and 6h). The role of TiO2 content and sintering time on the
microstructural properties and density of final products were investigated.

Abstract

Bu çalışmada, Seydişehir α-Al2O3,TiO2 kolloidal parçacıklar ile sol-jel yöntemiyle kaplanmış ve α-Al2O3’nın sinterlenebilirlik özellikleri rapor edilmiştir. Yıkama işlemi ile kirlilik miktarını azaltmaya, kalsine ile dönüşümü stabilize etmeye ve jet değirmen öğütme ile α- Al2O3’nın tane boyutu azaltılmaya çalışılmıştır. TiO2 sol-jel yöntemi kullanılarak kaplama ile Al2O3'ün yoğunluğunun arttırılması amaçlanmıştır. Seramik tozları kuru preslenmiş, farklı saatler (1 saat, 3 saat ve 6 saat) boyunca 1580 0C'de sinterlenmiştir. TiO2 içeriğinin ve sinterleme süresinin nihai ürünün mikroyapısal özellikleri ve yoğunluğu üzerindeki rolü araştırılmıştır.
