    Abstract: For bentonite clays and kaolin, the studies were carried out to establish a correlation between the
moisture at the plastic limit determined by traditional laboratory methods and the complex permittivity
determined by the method of resonance measurements in the microwave range of electromagnetic waves at
frequencies of 1.4-1.7 GHz. The effect of crystallization of water located between clay particles on the clays
electrophysical properties is studied.
