Dielectric dispersion in the mechanically activated fine-dispersed heterogeneous systems

With the help of the dielectric sensing methods we researched the influence of granulometric composition, moisture, temperature, constant electric field on the actual value of dielectric permittivity and loss-angle tangent for ultra-thin micas of industrial deposits of coal in Eastern Siberia in the area of low frequencies. Experimental data that show capability of the water films to significantly change electrophysical properties of dispersed micas are presented. The study of the fine-dispersed phlogopite micas samples allowed detecting the effect of the dielectric permeability dependence on the granulometric composition of micas particles.
