A novel ternary borate glass system was synthesized by utilizing standard melt quench approach. All of the samples went through an annealing process for 6 hours to remove retained thermal strains present in glass structure. XRD test revealed that the samples were indeed glassy. Density was determined at room temperature; oxygen packing density (OPD) and molar volumes were calculated. Both density and OPD changes followed recognizable patterns that complemented the Mixed Transition Effect (MTE). The electrical resistivity was measured by Keithley two probe instrument in range of temperatures 308-523K and conductivity was estimated. These glasses are unique among single TMI doped glasses systems in that they have exceptionally high conductivities in 10-5 to 10-3 (Ωm)-1 range, while still maintaining low activation energies. The conductivity data was analyzed through Motts small polaron hopping (SPH) model at higher temperature region T > θD/2 and remaining data was analyzed by employing the VRH models by Mott’s, Mott-Greave’s at lower temperature region T < θD/2. Respective polaron related parameters such as small polaron radii, the average distance between transition metal ions, TMI density, mobility etc. were estimated. The very first time, by using a MnO2-V2O5 dopant ternary borate glasses have been synthesized. Studies on high-and low temperature DC conductivity investigations have revealed the presence of a mixed transition effect (MTE).

abstract = {A novel ternary borate glass system was synthesized by utilizing standard melt quench approach.

Density was determined at room temperature; oxygen packing density (OPD) and molar volumes were calculated. Both density and OPD changes followed recognizable patterns that complemented the Mixed Transition Effect (MTE). The electrical resistivity was measured by Keithley two probe instrument in range of temperatures 308-523K and conductivity was estimated. These glasses are unique among single TMI doped glasses systems in that they have exceptionally high conductivities in 10-5 to 10-3 (Ωm)-1 range, while still maintaining low activation energies. The conductivity data was analyzed through Motts small polaron hopping (SPH) model at higher temperature region T > θD/2 and remaining data was analyzed by employing the VRH models by Mott’s, Mott-Greave’s at lower temperature region T θD/2.
