摘要：

It is demonstrated that the permittivity (dielectric constant) of powders suspended in suitable liquids can be determined by impedance spectroscopy techniques. A prior knowledge on the solids loading of particles in the slurry, the permittivity, and the electrical conductivity of the liquid is not required to determine the permittivity of particles by this technique. Some theoretical considerations of this method supported with experimental studies are described toward understanding of the physical phenomena involved with the characterization of slurries, which implemented to determine the permittivity of particulate materials.
