説明

<jats:p>Measurements of the complex permittivity of clay-sand slurry containing fine-milled mineral particles suspended in water carried out at 9.4 GHz show a marked dependence on both temperature and moisture content. The character of these relations is similar to that obtained for pure water. Permittivity and specific gravity of a slurry in the range interesting for technical activity are little affected by its chemical composition. On the basis of measurements carried out for five kinds of technological slurries a simple model for quick analysis of their properties is presented. The model consists of two separate layers: water and dry mineral inclusions, the thickness of which is proportional to the volume content in the suspension. Resultant permittivity of the biphase water suspension is equal to the sum of square roots from permittivities of both constituents, multiplied by their volume filling factors. Experimental results agree with those calculated from such simple formula within accuracy of measurement (dielectric constant within 2%, loss factor within 5%).</jats:p>
