✦ Synopsis

Abstrae-Measurements of the electrical conductivity, k, of fluidixed beds have been extended to cover the full range of conductivity ratio of the two phases, (I, and a wide range of dispersed phase volume fraction, f. The Maxwell relation is shown to hold adequately provided a and f are not both high, when all available theories may greatly underestimate the value of k. The results can be applied to describe thermal conductivity and diffusion in composite systems, provided that convective effects can be neglected.
