Sintering Properties of Slip Casted Greek Red Mud Bodies
Öz
Red mud is a solid waste residue of the digestion of bauxite ores with caustic soda for alumina production. There are several red mud sources in the world. The aim of this study was to identify the sintering conditions and technological properties of slip casted Greek red mud bodies. Chemical analysis of used greek red mud was determined by XRF. Slip casted samples were prepared with 40 vol. % solid content and sintered at 900, 950 and 1000 °C for 2h, seperately. Sintering and technological properties were determined by measuring density, firing shrinkage and water absorption. Structural characterization was carried out with scanning electron microscopy (SEM) and X-ray diffraction studies. The best density, water absorption, firing shrinkage values were obtained with Greek red mud body sintered at 1000°C. Artistic glaze was applied onto the Greek red mud bodies sintered at 1000°C. Glaze-body interaction were determined.
