“…The point of slope change of endothermic peak in DTA curve indicates the glass transition temperature T g as marked in the DTA profile. Generally, the glass transition Tg is known to depend on several independent parameters as the band gap, bond energy, effective molecular weight, the type and fraction of various structural units formed and the average coordination number (18). Exothermic peak is identified as the crystallization temperature T c and the glass stability factor has been measured from the T g and T c values of DTA curve by using the relation S= T c -T g .…”

Glass samples belonging to the general formula 60B2O3-(40-x) MnO2-xMgO with x=2,4,6,8,10 mol% were prepared by the conventional melt quenching technique was studied. Characterisation of the system was carried out using XRD, FTIR, DTA analyses. XRD confirms the amorphous nature of the samples. Thermal and spectroscopic behavior of the glass system was studied by DTA and FTIR analyses. FTIR reveals the presence of various functional groups present as well as the conversion of BO3 to BO4 units on the subsequent addition of modifier MgO. DTA gives an insight into the glass transition temperature, crystallization temperature, melting temperature and hence the stability of the glasses.

“…Another interesting Se based glassy alloys are Se-Sb alloys owing to their electrical, optical dielectric and thermal properties. Mehta et al have reported the thermal characterization with calorimetric measurements for some Se-Sb alloys [25]. They reported the Hruby number, which is the strong indicator of glass forming tendency, thermal stability parameter and the values of crystallization enthalpy and entropy.…”

“…Dietzel [91] has introduced the first GFA criterion D T = T c -T g and Hruby [93] developed the important H R GFA crite− rion (H R = T c -T g / T m -T c ). Hruby parameter described that GFA criterion has the additional advantage to express the thermal stability of glassy materials [94,95]. GFA and ther− mal stability of vitreous materials can be established from the DSC measurement analysis.…”

Amorphous semiconductors or chalcogenide glasses are the key materials in modern optoelectronics to make comfortable life of our society. Understanding of physical properties (like microstructure, thermal, optical, electrical) of these materials is important for their different uses. Predominant study of physical properties of the metal containing multicomponent chalcogenide glasses have attracted much attention, due to their interesting variable features and wide range of structural network modifications. Structural modifications in these materials are usually described with respect to the values of structural units (or average coordination number). In significance to this, the present work demonstrates the chronological development in the field of chalcogenide glasses along with scanning electron microscopy (SEM) morphologies. Optical, electrical and thermal correlative properties of recent developed Se93−xZn2Te5Inx (0 ≤ x ≤ 10) metallic multicomponent chalcogenide glasses are discussed. Variation in SEM morphology, refractive index (n), extinction coefficient (K), optical energy band gap (Eg), electrical conductivity (σav), crystallization activation energy (Ec) and glass forming ability (GFA) with structural units of Se-Zn-Te-In glasses have been demonstrated in this study. Subjected materials thermal, optical and electrical parameters have been achieved higher and lower in a respective manner at the threshold structural unit value 〈r〉.
