Rationale for Introducing an Additional Term into the Glass Transition Criterion

  • Published:
Inorganic Materials Aims and scope

Abstract—

A modification to a previously proposed glass transition criterion is analyzed and substantiated in terms of the delocalized atom model. The atom delocalization energy in sodium germanate, alkali silicate, and sodium borate glasses is shown to be a linear function of their glass transition temperature.
