“…Complete conductivity spectra of the hexagonal b-phase of silver iodide have been published earlier, for temperatures of 300 K and above. 66 At those temperatures, the onset of the dispersion is found to occur in the radio-frequency regime. We have now extended our studies to lower temperatures, in order to observe the onset of the dispersion of s(n) at frequencies below a few MHz and thus to determine the shape of the conductivity isotherms with higher precision.…”

Thermodynamic Properties of AgCl and AgBr

et al. 2008

Temperatures and enthalpies of fusion as well as the heat capacity of silver chloride and silver bromide were measured by differential scanning calorimetry. A polynomial heat capacity dependence on temperature was used to fit the experimental data. The thermodynamic functions of AgCl and AgBr were calculated by combining these heat capacity results with the entropy at 298.15 K, temperatures, and enthalpies of fusion.

“…Examples are materials with intrinsic Frenkel or Schottky defects, such as alkali and silver halides. 131 In these materials, the interactions between the small number of defects are weak and the defects are partly bound to counter charges. Therefore, on short time scales the defects carry out localized movements close to the counter charges.…”

Fundamental questions relating to ion conduction in disordered solids

et al. 2009

View full text Add to dashboard Cite

A number of basic scientific questions relating to ion conduction in homogeneously disordered solids are discussed. The questions deal with how to define the mobile ion density, what can be learned from electrode effects, what is the ion transport mechanism, the role of dimensionality, and what are the origins of the mixed-alkali effect, of time-temperature superposition, and of the nearly-constant loss. Answers are suggested to some of these questions, but the main purpose of the paper is to draw attention to the fact that this field of research still presents several fundamental challenges.
