Glass of composition 10PbTiO3–60V2O5–30B2O3 in mol% was prepared by conventional melt quenching technique. Annealing process was applied to the glass samples at temperature close to crystallization temperature Tc for different time intervals 1, 2, 4, 8 and 24 h, respectively to obtain glass ceramic nano-composites. The samples densities were measured by Archimedes method. Differential scanning calorimeter data confirms the amorphous nature and shows high homogeneity of the glass sample. Transmission electron microscopy and X-ray diffraction were also used to confirm the amorphous nature and the existence of nano crystallites embedded in the glass matrix. Glass ceramic nano-composites show giant enhancement in electrical conductivity (about 6 orders of magnitude) as a function of heat treatment times. This enhancement of conductivity is attributed to the increase in crystal size which …
