Differential thermal analysis (DTA) and X-ray diffraction (XRD) have been employed to investigate the copper oxide content dependence of the glass transition temperatures data, activation energy for the glass transition Et, glass stability GS, fragility index Fi, the glass-forming ability (GFA) and crystallization behavior of {(100−x) mol% Li2B4O7–x mol% CuO} glass samples, where x=0–40 mol% CuO. From the dependence of the glass transition temperature Tg on the heating rate β, the fragility, Fi, and the activation energy, Et, have been calculated. It is seen that Fi and Et are attained their minimum values at 0
