Internal friction measurements of soda aluminosilicate glasses, the physical properties of which were reported in Part I of this series, are discussed. The low‐ and intermediate‐temperature internal friction peaks were studied in detail and are shown to be due to the stress‐controlled movement of the sodium and nonbridging oxygen ions, respectively. A close correlation was found between the temperature shift of the low‐temperature peak and the activation energy for electrical conduction in the soda aluminosilicate glasses. The magnitude of the low‐temperature peak was found to depend more on the structural environment of the sodium ions than on the actual soda content. Changes in the intermediate‐temperature peak are explained on the basis of the structural model proposed for these glasses.
