The superionic properties of the compounds RbAg 4 I 5 , KAg 4 I 5 and KCu 4 I 5 have been investigated by powder neutron di4raction and complex impedance spectroscopy. RbAg 4 I 5 and KAg 4 I 5 have room-temperature ionic conductivities of ؍ 0.21(6) and 0.08(5) ؊ 1 cm ؊ 1 , respectively, which inc
The influence of grain boundaries on dc and ac conductivities of polycrystalline RbAg,I, and Ag,SBr was studied in the temperature range 15 K < T < 298 K using low-frequency EIS and high-frequency waveguide measurements. A change of the ion conduction mechanism is found at a transition temperature i
