Effect of pressure on ionic conductivity in rubidium silver iodide and silver iodide
The effect of pressure on the ionic conductivity of RbAg4I5 and AgI has been measured, using single crystals and polycrystalline samples, up to pressures of 6 kbar. The activation volumes for motion in cr-RbAg4I5 and B-RbAgI5, respectively, are -0.4 ±.2 cm3/mole and -0.2 ±.l cm3/mole. In 4a-AgI, …

Raman scattering studies in the isostructural family of the solid electrolyte rubidium silver iodide
… modes of the iodine tetrahedra around the silver ions. The spectra also show low frequency scattering out to about 60 cm-1. At high temperature the low frequency spectrum consists of a quasi-elastic peak about the laser line plus a shoulder at 20 cm -1 This shoulder has roughly equal T2 and …

Microwave-Frequency Conductivity of Alpha Silver-Iodide, Microwave Spectroscopy of Hydrogen-Bonded Species, and Design of a High-Temperature Nozzle Source
Chapter I reports the measurement of silver ion conductivities in the alpha phase of silver iodide over the frequency range 4 to 40 GHz. The conductivity is independent of frequency over this range and has a value of 1.2 (ohm-cm)('-1) at 429 K. These results are combined with other recent …
