RT Journal Article T1 Posibilidades cerámicas de las pizarras Paleozoicas de Almuradiel (Ciudad Real) T1 Ceramic posibility of Paleozoic shales from Almuradiel (Ciudad Real) A1 Parras, J. A1 Sánchez, C. J. A1 Luque, F. J. A1 Rodas, M. A1 Acosta, A. AB Raw materials used in the manufacturing of white stoneware mainly consist of illitic and kaolinitic clays, containing <7.5% of iron oxides. Quarlzitic sands and feldspars are commonly added to improve their physico-chemical properties. This paper deals with the ceramic applications of altered shales (illitic and pyrophyllitic clays) and with the influence of different additives on their ceramic characteristics.
