Abstract
The frequency dependence of the permittivity of water in calcium kaolinite (clay) is measured. It is shown that two mechanisms contribute to dipole re laxation of water. One refers to water in the free volume of pores in the c lay. The other is associated with bound water covering the porous surface. Experimental data are treated in terms of a fractal model of the medium. Th e frequency dependence of the permittivity in a wide range of water content in the clay is accounted for theoretically.
