The free‐volume fraction (V f ) defined by Simha and Boyer was measured for network‐forming oxide glasses in the systems P 2 O 5 ‐(GeO 2 , TeO 2 ,Sb 2 O 3 .V 2 O 5 ). The V f values varied from 0.06 to 0.25. The systems P 2 O 5 ‐TeO 2 : and P 2 O 5 ‐Sb 2 O 3 have V f ∼0.1, which is near the magnitude of the free‐volume fraction for normal metaphosphate glasses and many organic high polymers.
