✦ Synopsis

The ionic conductivity of some silver fluorides and oxyfluorides with either cryolite or chiolite-related structures has been investigated. Despite the high polarizability of the Ag+ ion, the ionic conductivity is relatively low. Several conductivity mechanisms have been considered and discussed.
