Abstract Details

2014, PhD, University of Cincinnati, Engineering and Applied Science: Electrical Engineering.
We examine the physical properties of (B2O3)5(TeO2)95-x(V2O5)x, a Heavy Metal Oxide (HMO) glass and the GexS100-x binary glass using calorimetric (MDSC), optical (FT and Dispersive Raman), volumetric (Molar Volume) and Electrical conductivity measurements. Calorimetric data provides direct evidence of square-well like reversibility windows (RWs) in the 23.5% < x < 26.5% range for the HMO and in the 19.3% < x < 24.9% range for Ge-S glass systems. The space filing nature of networks formed in these windows, the existence of optical or electrical conductivity thresholds near the walls of these windows confirm that RW glasses represent rigid but unstressed networks representing Intermediate Phases in respective glass systems, identified in the present work for the first time.
