Abstract

Using the model of delocalized atoms, an explanation is offered for the linear dependence of the microhardness of inorganic glasses on their glass transition temperatures. In these systems, the elementary volume required for the delocalization of atoms is determined by the nature of the bridging atoms and bridging valence bonds. An estimate of the volume of atom delocalization is given, based on data for the glass transition temperature and microhardness.
