Characterization of two clay minerals of the Niger River Valley: Téra and Boubon

Written by sctunisie no comments

This work presents some results of a characterization by X-ray diffraction (XRD), infrared spectroscopy (IR), Scanning Electronic Microscopy (SEM), Thermo gravimetric analysis (TGA) and differential thermic analysis (DTA) of two samples of clay minerals collected from Téra and Boubon in the valley of the Niger River. The results reveal that these samples contain a significant amount of kaolinite ranging from 60.99 to 61.61 %. We note also, the presence of Illite at low quantities.
