The internal friction of only network‐forming oxide glasses containing a P 2 O 5 component, i.e., in the systems P 2 O 5 ‐GeO 2 , P 2 O 5 ‐TeO 2 , P 2 O 5 ‐Sb 2 O 3 , and P 2 O 5 ‐V 2 O 5 , was measured as a function of temperature by a free torsional vibration method. P 2 O 5 ‐TeO 2 and P 2 O 5 ‐Sb 2 O 3 glasses exhibited clearly high‐temperature peaks in a plot of internal friction vs temperature in spite of the absence of nonbridging oxygens and network modifiers. Therefore, we conclude that the high‐temperature peaks appeared when strong and weak parts coexisted in the network structure.
