Abstract
The complex electrical impedance of Na3H(SO4)(2) along the b(m)-axis h as been measured from 25 degrees to 316 degrees C in the frequency ran ge 4 kHz-40 MHz. The temperature dependence of the electrical conducti vity shows remarkable changes in the temperature range 160 degrees C-2 60 degrees C. The sample crystal becomes a fast ionic conductor above 260 degrees C. The conduction mechanisms of proton and sodium ions in the different phases are analyzed in detail with respect to the struct ural features of the sample crystal. (C) 1998 Elsevier Science BN.
