Evaluation of Bagasse Ash for Application in Glass Manufacture
Abstract
Bagasse ash results from burning bagasse, a matted cellulose fiber residue from sugarcane that has been processed in sugar mills. In this paper, Bagasse ash has been chemically characterized in order to evaluate the possibility of its use in glass manufacture. The result of X-ray fluorescence (XRF) showed the ash to contain SiO2 - 31.67%, K2O - 31.41%, P2O5 - 8.14%, MgO - 4.89%, CaO - 3.92%, Na2O - 3.17%, Fe2O3 - 1.23% the ash was normalized as no LOI was carried out. Qualitative and quantitative X-ray diffractometry (XRD) for determination of composition and presence of crystalline material, showed the presence of silica in free and various combined states and potassium magnesium carbonate. Scanning electron microscopy (SEM/EDS) at 100µm and 300µm showed clusters of spherical and rod like microstructure at different spectra
