摘要：

The relation between fast ion conductivity, glass forming ability, and structure in (AgI)x(AgPO3)1-x glasses has been studied using neutron and x-ray diffraction and extended x-ray-absorption fine structure spectroscopy. Reverse Monte Carlo models based on the data show that AgI doping causes an increase in free volume available for Ag+ motion, which leads to the considerable increase in conductivity but also limits the glass forming range by decreasing ionic cross-linking of the phosphate network. Analysis of the available free volume shows a percolation transition in the connectivity of Ag+ pathways for 0.2<x<0.3. © 1995 The American Physical Society.
