- Mechanical percolation and structural transition in Ge–S–Bi bulk glasses
- Published at:Materials Letters, Volume 57, Issue 1, November 2002, Pages 219-222
The compositional dependence of the mean atomic volume, Va, and the packing density, ρp, of the GexS94−xBi6 glassy system, in the range 14≤x≤26 (x in at.%), have been investigated. Particular features in the compositional dependence of these physicochemical properties on the bond density, n, have been found. Specifically, at n=2.46, Va and ρp exhibit a minimum and a maximum, respectively, whereas at n=2.56, Va displays a maximum and ρp passes through a minimum. These features are explained using the topological arguments proposed in Phillips'–Thorpe and Tanaka's models.
