摘要：

Because of the disordered structure, glass has many voids termed free volume, in which no atoms or ions exist. Previously, the present author has defined the free volume by the stacking of atomic cubes. As a result, the free volume varies depending on the values of atomic radii chosen. In the present study, the 'true free volume, which can be determined independently of the choice of atomic radii, is derived for alkali silicate and phosphate glasses.
