Modificación microestructural de minerales arcillosos en ball clays de Teruel mediante tratamiento térmico

Abstract: El objeto de este trabajo es estudiar la variación de límites de Atterberg en el tratamiento térmico de ball clays de la zona minera de Teruel a temperaturas inferiores a la de deshidroxilación de los filosilicatos presentes en las mismas. Dicha variación consiste en ligeras disminuciones del límite plástico y descensos más importantes en el límite líquido, y puede relacionarse, en el caso aquí considerado, con el aumento del tamaño de cristalito de los filosilicatos presentes (caolinita e illita, en este caso… Show more

“…The influence of thermal treatments below the dehydroxilation temperature of clay minerals of ball clays (kaolinite and illite) on the Atterberg limits of these treated materials was studied [249]. The observed variations (slight decreases in the plastic limit and more important decreases in the liquid limit) were attributed to the increase in crystallite size of the present main clay minerals (kaolinite and illite), as was found through a simplified X-ray diffraction microstructural analysis and via field emission scanning electron microscopy.…”
