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.spaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ClaysCeramic raw materialsPaleozoic shalesStonewarejournal articleopen access
