The upper Cretaceous succession from Northeast Aswan-Egypt consists of the Nubia group (Abu Aggag, Timsah, and Umm Barmil formations). This work is aimed at characterization and evaluation of refractory properties of some selected clay deposits in Northeast Aswan, Egypt to ascertain whether its suitability as a refractory material and for relevant application in Egyptian manufacturing industries. The ceramic properties depend on the clay mineral contents and the degree of crystallinity. The chemical and mineralogical composition have indicated that iron and titanium oxides (hematite and anatase) are considered accessory (coloring) minerals. No emissions of HCl and SO2 to the atmosphere were noticed through the treatment process of these clays that indicates it is environmentally safe. The primary physical properties (e.g. apparent porosity, water absorption, apparent specific gravity, and bulk density) were used to evaluate the product quality and to determine the industrial applications of the different refractory products.
