PHYSICO-CHEMICAL INVESTIGATIONS OF SOME MYSORE CLAY SAMPLES Part I. Determination of the Mineral Constituents of Clays

Abstract

The mineralogical composition of five Mysore clay samples and one Czechoslovakian sample has been calculated from the results of chemical analysis and compared with the data obtained by differential thermal analysis and determinations of base exchange capacity. Fourof these samples are found to be kaolins, one a halloysite and the other a mixture of kaolin and montmorillonite. The relative merits of B.E.C.and the thermal curves for the determination of the clay minerals are discussed.
