Extraction and Characterization of Silica from Reeds Biomass (Imperata cylindrical) in Various Annealing Temperature

Reeds biomass has been successfully extracted. It calcinated with annealing temperatures at 800 °C (A800), 850 (A850), and 900 (A900). The x-ray pattern showed that it a cristoballite (SiO2) crystal structure. band gap energy values are 3.8 eV, 3.7 eV 4.7 respectively. FTIR spectra show the groups silanol, siloxane, monohydride. Quantitatively, provide results to determine optical properties dielectric functions which indicate shift longer wavelengths an increase in temperature. morphology gives different image where particles formed flakes aggregates (A850) porous Full Text: PDF References A.
