Physico-chemical Characterization of Siliceous Sands from Houéyogbé in Benin Republic (West Africa): Potentialities of Use in Glass Industry
Résumé :
Physico-chemical characteristics of different silica sands from Houéyogbé municipality were evaluated. The results revealed that these sands contain a high percentage of silicon dioxide (SiO2), with a value approximately equal to 98.4 wt.%. Low Alumina content (<1.18 wt.%) and minor oxides such as Fe2O3, Na2O, K2O and TiO2 were also present (< 0.6 wt. %) in the samples. In all cases, the grain size distributions of the samples fall within the recommended size range for glass making. There are two major fractions: first between 106 µm - 212 μm and then in the range of 212 µm - 400 μm. Furthermore, comparison of these results with standard criteria shows that the samples are fully capable for use as source of SiO2 for glass making (flat glass, colored glass), may be used for concrete making and are usable in foundry or in the ceramic industry
