Intellectual Challenge

The discovery of amorphous, or glassy, metallic alloys in 1959 posed an intellectual challenge. How can one describe the structure of glasses when there is no long-range periodicity? What can the structure tell us about why certain metal alloys form glasses more easily than others? First, some universal characteristics, if any exist, of the structure metallic glasses needed to be found. A convincing model was proposed for the structure of metallic glasses based on Bernal’s dense random packing (DRP) structure. Central to this proposal is the idea that the structure of metallic glasses is that of the random filling of space by non-interacting identical spheres. In this model, strongly directional interatomic bonds do not play an important role in determining the structure of metallic glasses. This model is hpwever in conflict with one proposed by Chen, which correlates increased glass formability with increased chemical interaction between dissimilar atoms.

B2o3 Glass

With in glass forming region of Li2O–WO3–B2O3 glass system, a particular composition 40Li2O–5WO3–(55 –x) B2O3 : x V2O5 (with x ranging from 0.2 to 0.8, all are in mol.%) is chosen. The DSC traces are obtained to identify the glass transition temperature ( Tg ) and the glass forming ability of all the glass samples. The ESR and IR spectra portray the local structure of the glass system and valance states of the vanadium ions in the glass matrix. As the content of V2O5 increases up to 0.6 mol.% in the glass system, a gradual conversion of vanadium ions from V5+ state to V4+ state is observed, causing the depolymerization in the glass matrix by the transformation of several glass forming units BO4 → BO3 and WO4 → WO6 .
