Thermoelectric power of silver-containing glasses

Abstract

Thermoelectric power measurements were made on both silver oxide-containing glasses and a silver iodide-containing glass. The latter is known to be a superionic conductor. The value of the heat of transport deduced from the temperature dependence of the thermoelectric power was zero for the former glasses while for the latter glass it was non-zero, 3.9 kcal/mol, which is nearly equal to the activation energy for d.c. conduction, 4.2 kcal/mol. These results were discussed in terms of the conduction mechanism.
