Abstract: | Tellurium oxide glasses were prepared by the hammer and anvil technique. The glass systems are (0.85TeO2 + 0.15Z), where Z = K2O, TiO2, V2O5, MnO, Fe2O3, CoO, NiO or CuO. A second group is a ternary system 0.85TeO2+(0.15 − x)TiO2 + xFe2O3) with x=0.0, 0.05, 0.1, 0.15 mol. X-ray diffraction, infrared spectroscopy and differential thermal analysis measurements were carried out. The present study showed the different glass-forming groups, the glass transition and crystallization temperatures as well as the crystallization processes. |
