Connectivity and glass transition in disordered oxide systems
Abstract
Angell's congruent bond lattice (CBL) model of topologically-disordered oxide systems is used to analyse the connectivity of disordered systems accounting for the threshold degree of connectivity below which the system has a fluid-like behaviour. This approach is used to treat the liquid-glass transition as a percolation phase transition in the system of broken bonds — configurons. Small radii configurons are revealed in strong oxide systems and larger radii configurons in fragile materials.
