Dependences on the Composition and a Comparison of Electrolytic Properties of Some Germanium-Containing Quasi-binary Salt Systems

Germanium-containing quasi-binary salt systems GeSe-GeI2 and NaI-GeI2 (GeI2 is a dopant) are studied by methods of electroconductance and x-ray diffraction analysis (XRDA). The conductivity isotherms combined with the XRDA data show that the domain of restricted solid solutions in these systems comes to 3 and 1 mol % GeI2, respectively. The maximal electrolytic admittance is observed at 2 and 0.25 mol % GeI2 in GeSe-GeI2 and NaI-GeI2 systems. The GeSe system has better ceramic properties, is less susceptible to water traces, and has higher conductivity and lower activation energy for conduction.
