摘要：

The preparation of Cs(1-x)Rb(x)HSO4 crystals allows study of the influence of lattice defects on the superionic conductivity. The superionic phase transition disappears above x = 0.33 and a major structural change takes place at x = 0.5. Above x = 0.9 ferroelectric ordering is observed below 250 K. Glassy phase containing S2O72- defects is easily obtained by quenching in the 0.3 < x < 0.8 composition range. The influence of alkali cation size on properties is discussed.
