Two-Stage Model of Silicate Glass Transition

After several decades of study, the nature glass state and transition remains controversial. This work describes a newly proposed two-stage model for silicate transition. The recognizes that there is cooling rate independent critical temperature Tc, separating two regions. coherent structures in regions change along different paths. All observed dynamic features result from structural rearrangements process. According to model, can be recognized as second-order phase following an incomplete first-order will first describe then apply silica glass, well binary ternary transitions.
