The present work is devoted to the ternary system of heavy metal oxide (PbO) based vanadium - titanium glasses in the chemical composition of 50V2O5. (50 - x) PbO. xTiO2 system with 4 ≤ x ≤ 13mol%. These glasses were prepared by heat treatment in air at 1000 ºC followed by melt quenching technique. It has been shown from X-ray diffraction (XRD) that these samples are of amorphous nature. According to TGA/ DTA and DSC analysis, decomposition pattern has been formulated to account for the weight losses observed. The FT-IR profile has revealed that the glass has both VO4 and VO5 units. The microstructure of glass specimen was characterized by scanning electron microscope (SEM) coupled with EDS analyzer.
