[en] In this study physical and chemical characterization of seven clay samples from Cameroon is reported. The various analysis show that the main clay mineral in all samples is smectite with a small amount of kaolinite; some non clay minerals as cristobalite, K-feldspars, plagioclase, ilmenite and quartz are also present. The Cation Exchange Capacities range from 24.2 to 62.0 meq/100g. The specific surface area range from 58 to 123 m2/g. The chemical composition of the clays is dominated by SiO2, Al2O3 and Fe2O3 whereas MgO and Na2O are present only in small quantities.
