Abstract
The Sr1-xMx''F2+2x (M'' = Th. U) solid solutions appear as characteriz ed by the same clustering process as the Ca1-xMx''F2+2x ones: progress ive transformation with increasing x of 4:0:3:3 clusters into 1:0:3: 0 clusters. Comparison of the short-range structure and electrical prop erties of the M1-xMxF2+2x (M = Ca, Sr; M'' = Th, U) solid solutions sh ows that the fluoride ion conductivity in these materials is essential ly bound to the mobility of charge carriers, whereas their number depe nds on structural constraints.
