POLARIZATION AND CONDUCTION OF CLAY WATER-ELECTROLYTE SYSTEMS

The polarization and conduction of clay-water-electrolyte systems in a low frequency electric field can be presented in terms of the Dukhin- Shilov double-layer polarization model and a resistor-in-series model. In an experimental program, the permittivity and conductivity of two natural Leda clays were measured at a frequency of 60 Hz. The results of permittivity measurements were in good agreement with the Dukhin-Sh ilov theory. The surface conductivity of clay particles was estimated through the measurements to clap mass and pore fluid based on the resi stor-in-series model.
