Abstrakt: In our previous paper, we have demonstrated the amorphous-glassy-crystalline-amorphous state phase transition of Li2SO4 crystalline samples at the number of shock pulses of 0, 1, 2, and 3, respectively. In the present work, we extend the study on the abovementioned sequence of phase transition in such a way that it is to be examined by the impedance spectroscopy. Based on the observations, the results of the respective spectra well-agree with each other depending on the number of shock pulses. The positional disorder of Li atoms and rotational disorder of SO4 units behave as observed in the impedance spectroscopy by the impact of shock waves such that the resultant significant changes (several orders of magnitude) are noticed in the ionic- conductivity of the titled sample. The conducting behavior of the titled sample with respect to its state is due to the existence of peddle–wheel and percolation mechanisms. [ABSTRACT FROM AUTHOR]
