Abstract
An automated technique has been developed which enables a rapid determination of the dielectric properties of a material over a wide range of temperatures and frequencies. The speed of data acquisition and the range of temperature and frequencies that can be investigated in a single experiment using this technique, exceed the capabilities of techniques currently employed for dielectric analysis. Frequencies for dielectric measurements can be pre-selected in increments over the range 50 Hz-1 MHz. Temperature range for these measurements extends from 25°C to 800°C. The present technique, which features extensive automation in data acquisition and processing, is illustrated by measurements on minerals and shales. The dynamic nature of the above technique also facilitates effective coupling with conventional thermal analysis techniques.
