A theoretical model was suggested which described misfit defect structures at crystal/glass interfaces. In the framework of this model, the two basic types of misfit defect which were distinguished were misfit disclinations (generated as extensions of parent disclinations present in the adjacent glassy phase) and dilatation misfit dislocations (contributing to accommodation of the dilatation misfit that was associated with differences between the characteristic interatomic distances in the adjacent crystalline and glassy phases). The elastic energy density of crystal-glass interfaces was estimated. The present model was rather approximate. However, it was expected to be used effectively in more detailed and accurate studies of crystal/glass interfaces and of the latter’s contributions to the properties of crystal-glass composites.
