Ionic conductivity in monophasic Ag2xNa2(1 − x)ZnSiO4 materials with 0 ≤ x ≤ 1

1996

Abstract Solid solution samples Ag 2 x Na 2(1 − x ) ZnSiO 4 with 0 ≤ x ≤ 1 have been prepared by heat treating powder mixtures of Na 2 ZnSiO 4 and Ag 2 ZnSiO 4 at 300 °C and characterised by X-ray powder diffraction. The ionic conductivity of the solid solution has been determined as a function of composition and temperature by means of impedance measurements. The ionic conductivity of the mixed-mobile ion compositions (0 ≤ x ≤ 1) shows no substantial deviation from the mutually similar conductivities of the end compositions Na 2 ZnSiO 4 and Ag 2 ZnSiO 4 , and neither activation energy nor conductivity pre-factor varies significantly with composition. The results indicate that the mixed-alk…
