Abstract

The complex electrical impedance of Na₃H(SO₄)₂ along the b_m-axis has been measured from 25°C to 316°C in the frequency range 4 kHz-40 MHz. The temperature dependence of the electrical conductivity shows remarkable changes in the temperature range 160°C-260°C. The sample crystal becomes a fast ionic conductor above 260°C. The conduction mechanisms of proton and sodium ions in the different phases are analyzed in detail with respect to the structural features of the sample crystal.
