摘要：

Coal fly ashes from paper industry in Thailand have been melted with addition of H3BO3 and Na2CO3 to obtain glasses. The compositions and structure of fly ash were analyzed by energy dispersive x-rays spectrometer (EDXRF) and x-ray diffractometer (XRD) respectively. The results show that, density and refractive index of glasses were increased with increasing concentration of fly ash. The molar volume result indicated that the glass structure was more compacted, with increasing of fly ash. The absorption spectra measured in the range of 200 - 2000 nm shown board peaks of Fe2+ and Fe3+ absorption around 450 and 1100 nm respectively. (C) 2012 Published by Elsevier Ltd.
