Fragility, DSC and elastic moduli studies on tellurite–vanadate glasses containing molybdenum
چکیده انگلیسی

Ternary xMoO3–40TeO2–(60 − x)V2O5 glasses with 0 ⩽ x ⩽ 60 (in mol%) have been prepared by normal melt quenching method. DSC curves of these glasses have been investigated. The glass transition properties that have been measured and reported in this paper, include the glass transition temperature (Tg), glass transition width (ΔTg), heat capacity change at glass transition (ΔCP) and calculated fragility (F). Thermal stability, Poisson’s ratio, fragility and glass forming tendency of these glasses have been evaluated, 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 calculation of Young’s modulus, bulk modulus and shear modulus, indicating a strong relation between elastic properties and structure of glass. Generally, results of this work show that glass with x = 60 has the highest shear, bulk and Young’s moduli which make it as suitable candidate for the manufacture of strong glass fibers in technological applications; but it should be mentioned that glass with x = 20 has higher handling temperature and super resistance against thermal attack.


► Thermal and elastic properties of xMoO3–40TeO2–(60 − x) V2O5 glasses have been investigated.
► Upon DSC experiment and Makishima Makenzie’s model, the glass with higher thermal stability has been introduced.
► Glass with x = 60 has the highest shear, bulk and Young’s moduli which make it as suitable candidate technological applications.
