| Abstract: | The partial substitution of Zn2+ for Ag+ in Ag4P2O7 leads to the formation of a wide glassy domain of composition [Ag4P2O7] (1−y) [Zn2P2O7] (y) with 0.20y0.87. The introduction of AgI in these materials results in a new series of glasses of formula [(Ag4P2O7)(1−y) (Zn2P2O7)(y)] (1−X) [AgI] (x), which domain for the composition y = 0.25 corresponds to 0x 0.64. The structure as well as the thermal and electrical properties of these materials are compared with those of the [AgPO3] (1−X) [AgI] (x) and [Ag4P2O7] (1−x) [AgI] (x) glasses. |
