CHEMICOMINERALOGICAL STUDY OF A MOROCCAN CLAY

A moroccan clay sample, traditionally used in the pottery, have been t he subject of a chemico-mineralogical study. For this purpose, the fol lowing techniques: x-ray diffraction, infrared spectroscopy, different ial thermal analysis, thermogravimetry and transmission electron micro scopy, were used. Some chemical analysis were also done. It was found that the clayey fraction consisted of a mixture of palygorskite and gl auconite. Quartz and dolomite are the main associated minerals.
