COMPOSITION EFFECTS OF Al2O3 ON FTIR AND DTA IN LITHIUM BORATE GLASSES

Lithium aluminum borate glasses of composition 35Li2O: (65-x) B2O3: xAl2O3 (where x = 0,5,10,15,20) were prepared by melting quenching technique and investigated by XRD, SEM, DTA and FTIR measurement. Differential Thermal Analysis showed that glass transition temperature changes due to change of composition. The FTIR analysis revealed that network structures of sample are mainly based on BO3 and BO4 unit.
