The Dielectric Behavior of Solids Embedded in a Homogeneous Medium

Abstract

Dielectric constant and tan δ of powdered crystal phases of alumina, quartz, and wollastonite were determined. Since it is very difficult to obtain dielectric measurements of very fine (powdered) crystals, a technique of embedding the solids in a homogeneous medium was used. The relationship between particle shape and volume present in the composite to the dielectric properties of such fine powders was in accord with that indicated by Niesel's theory.
