argyrodite, superionic conductor, ceramic, ionic conductivity, activation energy


(Cu0.25Ag0.75)7SiS5I-based superionic ceramics were fabricated by using the micro- and nanopowders. The XRD technique and microstructural analysis are applied for the structural studies of powders and ceramic samples. The impedance measurements of ceramic samples are carried out in the frequency range from 10Hz to 2 × 106 Hz and temperature interval from 292 K to 383 K. The contributions of ionic and electronic conductivities into the total electrical conductivity are determined, and their temperature dependences are investigated. The influence of the size effect on ionic and electronic conductivities and their activation energies in (Cu0.25Ag0.75)7SiS5I-based ceramics is studied.
