The dielectric spectra of moist specimens of bentonitic clay are measured within the frequency range from 1 to 15 GHz at positive and negative temperatures. The phase transitions in different types of water present in the clay specimen are investigated in the process of its freezing. The parameters of dielectric relaxation and conductivity of different water types in the specimen are determined. A thermal dielectric model for thawed and frozen bentonitic clay is developed.
