Preparation and Calculation of Variour Ionic Transport Properties in a Superionic Mixed Composite System [Cu2HgI4:0.2 AgI]:0.xCuI

A new superionic mixed composite system, [cu2hgi4:0.2 agi]:0.xcui, (x=0.2, 0.4,0.6 mol. wt. %), was prepared by conventional solid state reactions and [cu2hgi4:0.2 agi]mixed system was used as the host. electrical conductivity was measured to study thetransition behavior at frequencies of 100 hz, 120 hz, 1 khz, and 10 khz in the temperaturerange 90°-170 °c by a gen rad 1659 rlc digibridge. conductivity increased sharply duringthe b-? phase transition. as a result of increase in the dopant-to-host ratio, the conductivity ofthe system exhibited arrhenius (thermally activated)-type behavior. the phase transitiontemperature increased with an increase in the dopant concentration. activation energies forthe system in ev both for the pre-transition and post-transition phase transformations arereported. the addition of cui to [cu2hgi4:0.2 agi] shifted the phase transition of the host[cu2hgi4:0.2 agi], due to an interaction between [cu2hgi4:0.2 agi] and cui
