Calorimetric measurements for a heating-cooling cycle determine the transition temperature and enthalpy of the phases present in the KNO3compound. The effects correlated within the ionic conduction of the KNO3 compound were studied by impedance spectroscopy measurements in a frequency range from 0.1 to 10 MHz for a cooling cycle. The imaginary part of the impedance with a frequency between 200 and 100°C showed a displacement of the Debye-like peak in the lower frequency direction. This displacement indicates an increase in the relaxation times of ionic conductivity by jump. In the dielectric formalism module, the imaginary part showed an asymmetric peak as a correlation consequence in the cationic diffusion. Also the registers demonstrated ...
