Dielectric Thermal Analysis. Dielectric thermal analysis is an analytical technique that measures the dielectric constant and/or the conductivity of a substance as a function of temperature. The sample is situated between two metal plates in a programmable furnace and an alternating voltage applied across them. The current and its phase difference with respect to the applied voltage is measured and from the data the various electrical properties of the sample can be calculated.
