Abstract
Samples of solid electrolytes based on β-Pb F2 doped with ScF3 were synthesized. The dependence lg σT has been studied from 1/Т the samples received. Significant changes in electrical conductivity and enthalpy are observed at an impurity concentration of 0,05±0,02. It has been established that as the content of SсF3 molecules in a solid solution increases, the number of defective regions increases and at a certain impurity concentration their spatial overlap occurs. The formation of a closed three-dimensional network of the defect phase corresponds to percolation and is accompanied by a change (often sharp) in the conductivity and other properties of solid solutions.
