Abstract The experimental FTIR spectra and DSC curves of the ternary 40TeO2–(60-x)V2O5–xNiO glasses with 0 B x B 30 (in mol%) have been investigated. The glass transition properties that have been measured and reported in this paper, include the glass transition temper- ature (Tg), glass transition width (DTg), heat capacity change at glass transition (DCP) and Fragility (F). Thermal stability, fragility, and glass-forming tendency of these glasses have been estimated. Also, Poisson’s ratio (l) and IR spectra of the presented systems have been investigated, to determine relationship between chemical composition and the thermal stability or to interpret the structure of glass. In addition, Makishima and Makenzie’s theory was applied for determination of Young’s modulus, bulk modulus, and shear modulus, indicating a strong relation between elastic properties and structure of glass. In gen- eral, results of this work show that glasses with x = 0 and 30 have the highest shear and young’s modulus which make them as suitable candidate for the manufacture of strong glass fibers in technological applications; but it should be mentioned that glass with x = 30 has higher handling temperature and super resistance against thermal shock.
