The temperature dependences of the ionic electrical conductivity of fluorite-type (sp. gr.F   m3   ‾m$Fm\overline{3}m$,  Z  = 8) KDy 3 F 10  and KHo 3 F 10  single crystals grown by the Bridgman technique have been studied by impedance spectroscopy for the first time. The correlation between the conductometric and structural characteristics of K R  3 F 10  ( R  = Tb, Dy, Ho, Y) crystal family from the point of view of the observed size effect in the ionic conductivity is discussed. With decrease in the unit-cell volume  V  1F  per fluorine atom in a series of crystals with  R  = Tb, Dy, Ho and Y, the activation energy  E σ of ion transfer decreases from 1.57 to 1.16 eV respectively and the fluorine-ion conductivity value increases from 3.0 × 10 −5  to 4.4 × 10 −4  S cm at 773 K, i.e. the nature of the conductivity change is linearly antibatic. This phenomenon can be useful for developing approaches and search strategies for new ionic conductors.
