Abstract
In this work, the subbituminous fly ash (SFA) in Thailand has been investigated for their compositions and crystal structures. Borosilicate glasses were prepare from SFA , B2O3, Na2O and various concentration of Fe2O3 by melt quenching technique. The results have shown that the chemical composition comprised with SiO2, Al2O3 and Fe2O3. The crystal structures of SFA were raised of mullite and quartz phases. The density and refractive index values of glasses were found to increase with increasing of Fe2O3 concentrations. The hardness values have been decreased with increasing of Fe2O3 content. The absorption spectra are corresponding to ferric and ferrous ions in wavelength of 440 nm and 1,050 nm and the color of glasses are green to yellow.
