Glass formation and high conductivity in the ternary system AgI + Ag/sub 3/AsO/sub 4/ + AgPO/sub 3/: host to glassy AgI
Wide regions of glass formation have been found in the ternary system xAgI + yAg/sub 3/AsO/sub 4/ + (1 - x - y)AgPO/sub 3/. Glasses containing up to 75 mol % AgI can be formed in sections greater than 2 cm thick without signs of devitrification. Glass transition temperatures as high as 175/sup 0/C for glasses containing approx. 10 mol% AgI fall to approx. 45/sup 0/C at the highest AgI content. An equivalent ratio of AgI:N is defined and it is found that, for all glass-forming compositions, the electrical data as expressed in the Arrhenius form, sigma = A exp(-E/sub act/RT), log (sigma/omega cm)/sup -1/), log (A/omega cm)/sup -1/), E/sub act//(kcal mol/sup -1/), and additionally T/sub g/K, can be described as linear functions of N. These data are used to give support to the view of these glasses as being hosts to a liquidlike AgI giving rise to the high conductivity they exhibit, as high as 0.0143 (omega cm)/sup -1/ at room temperature for glasses containing the maximum AgI. Finally, from these linear relationships, functions for the mobility ..mu.. and number of the mobile Ag/sup +/ cations n are developed. 29 references, 8 figures, 2 tables.
