Compounds of the argyrodite family are valuable environmentally friendly functional materials with mixed ion-electronic conductivity, thermoelectric, photovoltaic, optical, and other properties. This paper presents results a thermodynamic study Cu8GeS6 Cu8GeSe6 compounds - representatives this using EMF method Cu4RbCl3I2 solid electrolyte in 295-430 K temperature range. From measurement data, partial molar functions copper were calculated both crystal modifications compounds, undergoing...
Phase equilibria in the Ag8GeS6-Ag8GeTe6 and Ag8GeSe6-Ag8GeTe6 systems were studied using differential thermal analysis powder X-ray diffraction technique. The T-x phase diagrams constructed. It has been found that both are partially quasi-binary characterized by formation of continuous series substitutional solid solutions between Ag8GeTe6 high-temperature cubic modifications Ag8GeS6 Ag8GeSe6. When formed, temperatures polymorphic transitions these compounds decrease. This leads to...
Argyrodite family compounds and phases based on them are valuable ecologically friendly functional materials that exhibit a number of propreties, such as thermoelectric, photoelectric, optical, other. On the other hand, having Cu+ Ag+ ion conductivity, they ionic conductors, can be used electrochemical sensors, electrodes, or electrolyte in solid-state batteries, displays, etc. In present paper, phase relations Ag8SiS6–Ag8SiTe6 system were studied by differential thermal analysis X-ray...
Solid-state equilibria at 800 and 300 K in the 6Ag 2 S+Ag 8 SnSe 6 6Ag Sе+Ag SnS system which is of interest from point view obtaining new mixed ion-electron conductors were studied by DTA, XRD SEM methods.According to results obtained it was shown that reversibly reciprocal characterized formation continuous (800 K) or wide (300 regions substitutional solid solutions along boundary systems Ag S-Ag Sе -Ag .
