Evaluation and surface modification of the Egyptian clay of Kattamia

Abstract

A wide range of clays are presently available in Egypt. These clays are potentially economic substances as they contain minerals such as montmorillonite, kaolinite and illite. The x‐ray flourescence and the thermal gravimetric analysis (TGA) were calculated for the clay sample under consideration. The modification of the clay surface was achieved by using two different organic substances such as stearic acid and poly (methacrylic acid) solutions. It was found that the modification process improved the pigmentary properties of this clay.
