The ac response of the fluoride K3Fe5F15 has been investigated over the temperature range 293-773K using impedance spectroscopy. Impedance spectra show a curve that can be considered as an envelop of two depressed semicircles corresponding to bulk and grain boundary properties, and the modulus complex show two almost arcs...
