Optical Characterization of Fly Ash as a Glass Modifier in Potassium Borate Glasses


We have prepared alkali borate glass with fly ash as a network modifier (upto 5 mole %). Results have been compared with binary potassium borate glass and potassium borate glass with lead oxide as a modifier having same content as that of fly ash. Structural changes induced by addition of fly ash have been investigated by UV-VIS and FTIR spectroscopy, XRD and density measurements. This work can lead to future application of utilization and characterization of fly ash in glass forming materials.
