The measurement of electric properties of silicate minerals

Abstract

In the contribution a different approach to measurements concerning dielectric properties of powder materials and compact materials will be analysed. Measurements of relative permittivity at the frequency of 50 Hz will be performed and discussed provided that the powder is moistured at the beginning of the measurements. The conductivity measurements will be performed using the d.c. method. From the powder material separation point of view it is necessary to know its charging. At the end of the contribution, the new measure method related to the triboelectric charge determination will be introduced.
