Solid Electrolytes with a Glass‐Like Structure

Solid electrolytes formed by a formal partial substitution of iodide in AgI by a variety of oxoanions may be prepared in the vitreous state by fast‐quenching from the melt. Such materials, with few exceptions, are metastable and undergo thermal transitions into poorly conducting phases below the melting point. The conductance of a glassy electrolyte of this class was studied as a function of temperature and frequency. Features such as curved Arrhenius plots and high‐frequency dispersion are compared with similar observations in molten salt systems and the basis of such behavior is discussed.
