“…Zn 2+ exhibits lowest field strength (0.44) as compared to iron (Fe 3+ 0.79, Fe 2+ 0.49), manganese (Mn 4+ 1.07, Mn 3+ 0.77), and titanium (Ti 4+ or Ti 3+ , 1.00) ions. Consequently, ZnO possesses better tendency to act as a glass modifier and would produce larger number of non-bridging oxygen ions (NBOs), whereas TiO 2 is known to act as a glass former [16,17]. Thus, 15-Z is expected to have relatively weaker network connectivity and lower viscosity at high temperatures.…”

Various glasses are synthesized by melt quench technique. The addition of transition metal (TM) oxides into glasses paves the light on their crystallization and sinterability. The formation of different crystalline phases and their microstructures significantly influenced the conduction mechanism in these glass-ceramics. ZnO seemed to act as glass modifier, while TiO 2 appears to act as glass former in the present glasses. Other two TM oxides might have played a role as intermediate oxides. The present glassceramics are mixed conductors (ionic+electronic). MnO 2 -contained sample shows highest electrical conductivity while Fe 2 O 3contained sample show lowest conductivity. The observed results are interpreted on the basis of structural differences of the samples.
