STRUCTURE OF PARTLY QUENCHED MOLTEN COPPER CHLORIDE

The structural modifications induced in a model of molten CuCl by quen ching the chlorine component into a microporous disordered matrix are evaluated using the hypernetted-chain closure in Ornstein-Zernike rela tions for the pair distribution functions in random systems. Aside Fro m obvious changes in the behaviour of long-wavelength density fluctuat ions, the main effect of partial quenching is an enhanced delocalizati on of the Cu+ ions. The model suggests that the ionic mobility in a su perionic glass is enhanced relative to the melt at the same temperatur e and density. Only very minor quantitative differences are found in t he structural functions when the replica Ornstein-Zernike relations de rived by Given and Stell for a partly quenched system are simplified t o those given earlier by Madden and Glandt.
