<br/><br/> An electrical conductivity model of mixtures consisting of conducting and insulating powders is presented. It allows to describe the dependence of the electrical conductivity on the content of the conducting component for a wide range of the ratio of insulating and conducting particle dimensions. The model implies the possibility of obtaining strongly conducting composites with a low concentration of the conducting component.
