摘要：
The preparation of Cs(1-x)K(x)HSO4 compositions allows study of the influence of defects in the host lattice on the superionic protonic conductivity. The influence can be direct by modification of the structure and of the degree of static disorder or indirect in promoting glass formation on quenching. In all cases, phase transitions are spread out and electrical properties in the high and low-temperature phases are brought together. The vanishing of the superionic phase transition is related to the unit cell modification which reaches a critical level at x = 0.75.
