Description
The electrical conductivity of sodium–strontium germanate Na4SrGe6O15 (sp. gr. P63/m) has been studied by impedance spectroscopy in the frequency range of 102–4 × 104 Hz and a temperature range of 450–600 K. Na4SrGe6O15 crystals were obtained by hydrothermal technique in the Na2O–SrO–GeO2–H2O system (temperature t = 300–600°C and pressure p = 1.4 × 108 Pа in the dissolution zone). The ionic conductivity of ceramic Na4SrGe6O15 samples is σ = 2.2 × 10–6 S/cm (at 573 K), the activation energy of Na+ ion transfer is Ea = 0.70 ± 0.03 eV.
