TL;DR: In this paper, the authors examined features of primary and secondary relaxations in ionic glasses of the non-network type, using time domain and frequency domain relaxation methods, and obtained new data on the Ca(NO3)2-KNO3 system, and extended the measurements to a fast-ion conducting glass 40AgI·60AgPO3.
Abstract: We examine features of primary and secondary relaxations in ionic glasses of the “fragile” (non-network) type, using time domain and frequency domain relaxation methods. Using the Rheovibron in a static mode we obtain new data on the well-studied Ca(NO3)2-KNO3 system, and extend the measurements to a fast-ion conducting glass 40AgI·60AgPO3 We then study the latter glass, which is a fast cation conductor, and a PbF2-MnF2-Al(PO3)3 glass which is a fast anion conductor, in the deep sub-Tg regime where the mobile ions are being frozen out. Comparisons of electrical and mechanical relaxation in the same frequency range show the mechanical relaxation to be more exponential than the electrical relaxation and to have more symmetrical relaxation spectra which are not well-described by Kohlrausch-Williams-Watts function.
