Investigation of Mineralogy and Ceramic Technology Properties of Sivrihisar Kurtşeyh Sepiolites (Türkiye)

Abstract

In this study, the geology, mineralogy, and potential uses of the Sivrihisar sepiolite and dolomitic sepiolites of the Eskişehir region (Türkiye) for ceramic wall tiles were investigated. A geological map of the open pits in the village of Kurtşeyh and generalized stratigraphic sections are presented. Samples taken from the pit sequences were characterized in terms of their mineralogy by XRD (X-ray diffraction). Chemical and Thermal analysis of the raw materials was determined by XRF (X-ray fluorescence), Thermal analysis (TA), and Differential Thermal analysis (DTA). Besides these studies, the thermal properties and shrinkage (%), water absorption (%), and color (L, a, b) of the fired wall tile bodies were investigated to determine their technological properties. In light of all the analysis results, alternative body formulations were created, and these recipes were fired under wall tile conditions. The fired phases were then mineralogically characterized, and the physical and technological properties of the different bodies were studied. As a sum, 10% dolomitic sepiolite usage instead of İstanbul clays is suitable for manufacturing wall tiles.
