LONG TIME RELAXATION PROCESSES IN GLASSY SOLIDS. II. beta RELAXATION IN FAST ION CONDUCTING GLASSES.

The study of long time relaxation processes is extended to beta -processes due to mobile ions. Mechanical relaxation spectra in both mobile cation and mobile anion glasses are broader than for electrical relaxation and more symmetrical. Most probable relaxation time for mechanical stress is slightly longer than for electrical stress for the Ag** plus conducting glasses while the reverse is true for F** minus conducting glasses. The higher conducting Ag** plus glasses have the broader spectra for both types of stress. The systems studied were 40AgI multiplied by (times) 60AgPO//3, 50AgI multiplied by (times) 50AgPO//3, 50AgI-25Ag//2SO//4 multiplied by (times) 25Ag//2WO//4 and 70PbF//2 multiplied by (times) 20MnF//2 multiplied by (times) 10Al(PO//3)//3.
