Abstract

The scope of this study is to determine the different crystal formation in the 0.8TeO₂ + 0.2CdF₂ glasses heated with different rates to various annealing temperatures by using differential thermal analysis (DTA), X-ray diffraction (XRD) techniques, chemical analysis, optical microscope and scanning electron microscopy/energy dispersive spectroscopy (SEM/EDS). Different number of exothermic peaks were observed indicating the different crystallization or the transition of certain phases in the glass structure as the heating rate of DTA scans varied from 5 to 20 °C/min. On the basis of the XRD investigations α-TeO₂, γ-TeO₂ and CdTe₂O₅ crystalline phases were determined. SEM/EDS investigations of all the glasses revealed the presence of different phases correlated with the XRD analysis.
