The conductivities of glasses in this system were measured at pressures ranging from 0 to 10kbar, as were those of glasses which had previously been densified at 50kbar. All of the glasses exhibited a progressive decrease in conductivity with increasing pressure. The activation volumes for Ag+ ion migration lay between 2.8 and 2.1cm3/mol, and decreased with increasing AgI content. Similar decreases in conductivity were caused by densification; thus indicating that new glasses might be prepared so as to have properties which depended upon the pressure history.
