Abstract
Abstract Glass samples from the V2O5SrOB2O3 ternary system were prepared by the rapid quenching method. The glass formation region determined by X-ray diffraction analysis was in the range of V2O5 30 to 85 mol%, SrO 15 to 50 mol% and B2O3 0 to 40 mol%. The electrical conduction mechanism in these glasses is discussed in terms of the small polaron hopping theory by Mott. At temperatures higher than room temperature 1n σ versus T−1 is approximately linear and exhibits small polaron hopping conduction. However at temperatures below room temperature, the conductivity (σ) was proportional to T − 1 4 . This fact shows that the conduction may be due to variable range hopping (VRH).
