Abstract

The dependence of the electrical conductivity of a mixture of finely disperse graphite with quartz sand and moist quartz sand on the composition is investigated. It is shown that, in the region of critical and near-critical concentrations of the conducting component, the dependence is satisfactorily described by two power-law equations of flow theory with two different threshold values of the conducting-phase concentration. In this concentration range, the conductivity of the sandgraphite system is satisfactorily modeled by a lattice bond problem. The electrical transfer in the sand-KCl solution system may be modeled by a lattice point problem in the representation of the moist system as a mixture of dielectric particles coated with an electrolyte film (conducting particles) and dry dielectric particles (nonconducting particles).
