Thermal Analysis of LI2O-B2O3-AL2O3 Glass System

Abstract

Lithium aluminum borate glasses of composition 35Li2O: (65-x) B2O3 : xAl2O3 (where x = 0, 5, 10, 15, 20)

were prepared by melt quenching technique and investigated by XRD,SEM, and DTA measurement. XRD and SEM confirmed the nature of glasses. Differential Thermal Analysis showed that glass transition temperature changes due to change of composition. The thermal analysis revealed that mass loss of sample decreases with increase in mole percent of Al2O3 and the GFA parameters ∆Tx  and γ follow the same trends with GS parameter KH . The glass sample content of 15 mole percent of Al2O3 was higher thermal stability against crystallization.
