Phase transition and complex impedance studies of mechano-chemically synthesized AgI-cuI solid solutions

Solid solutions of AgIx-Cu1-xI (0.1 < x < 1.0) were prepared using mechanochemical technique. XRD measurement shows the AgI-CuI phase system at room temperature. DSC traces show that the superionic phase transition temperature increases from 149 degrees C to 376 degrees C upon addition of Cu....
