Structural Characterization of fly ash doped lithium borate Glasses JARNAIL SINGH1, GURMELSINGH1,NEETU CHOPRA2,GAGANDEEP SINGH3, and

Lithium borate glasses with fixed alkali content of 10 Mole % and different modifiers have been prepared. To compare the role of fly ash as a glass modifier the content of glass modifier PbO, Al2O3 have been kept same to 5 mole %. To investigate the structure FTIR and UV-VIS spectra of prepared samples have been taken. From optical data optical band gap and cutoff wavelength have been calculated. Density of prepared samples has been calculated by using Archimedes principle. Results have been compared with structure of binary lithium borate glass. This work can lead to future application of utilization and characterization of fly ash in glass forming materials. Key Words: Fly ash, Optical band gap. Glass modifie
