Abstract
Bu çalışmada Seydişehir Eti Aluminyum tesislerinden temin edilen atık dökümü kumu, başlangıç malzemesi olarak kullanılmıştır. Tedarik edilen bu malzeme üzerinden sol-jel yöntemi ile silika aerojel üretimi gerçekleştirilmiştir. Çalışmaların başlangıcında atık döküm kumuna sırasıyla XRD ve XRF analizleri yapılmıştır. Böylelikle başlangıç malzeme kimyasal bileşimleri tespit edilmiştir. Analiz çalışmalarını takiben atık döküm kumundan sodyum silikat çözeltisi elde edilmiştir. Daha sonra silika aerojel sentezleme çalışmaları için beş farklı pH değeri (2, 4, 6, 8 ve 9) uygulanmıştır. Son olarak uygun pH değeri belirlenerek silika aerojel modifikasyonu (Süperhidrofobik) gerçekleştirilmiştir. Sentezlenen silika aerojel malzemede sırasıyla yoğunluk ölçümleri, FT-IR analizi, temas açısı ölçümü ve SEM incelemeleri olmak üzere karakterizasyon çalışmaları gerçekleştirilmiştir. Uygulanan farklı pH değer ve deneyleri neticesinde, pH 8 değeri ile yoğunluğu en düşük silika aerojel içeriği oluşumu tespit edilmiştir.

Abstract
In this work, waste casting sand obtained from Seydişehir Eti Aluminum plants was used as starting material. Silica aerogel was produced by sol-gel method over this supplied material. As the beginning of the studies, XRD and XRF analyzes were performed on the waste casting sand, respectively. Thus, the chemical compositions of the starting materials were determined. Following the analysis studies, sodium silicate solution was obtained from the waste foundry sand. Then, five different pH values (2, 4, 6, 8 and 9) were applied for the synthesis studies of silica aerogel. Finally, the appropriate pH value was determined and silica aerogel modification (Superhydrophobic) was carried out. Characterization studies, respectively, density measurements, FT-IR analysis, contact angle measurement and SEM examinations were carried out on the synthesized silica aerogel material. As a result of applied different pH values and experiments, the formation of silica aerogel content with the lowest density with pH 8 value was determined.
