The conductivity was measured as a function of pressure. It was shown that the activation volume increased appreciably with increasing temperature and decreased with increasing pressure (table 59). The large increase in the activation volume as a function of temperature was attributed to the onset of a gradual transition to a solid electrolyte phase.
