Thermoelectric properties of carbonaceous solids

The application of thermoelectric measurements for the characterization of carbonaceous materials, like graphite and chars, can be helpful for monitoring the chemical/physical evolution of the material during gasification, which occurs upon steps of gas diffusion and heterogeneous chemical reaction at moderate and high temperature. The present article reports on an experimental research concerning the application of thermoelectric measurements for qualitative and semi-quantitative characterization of carbonaceous materials, like graphite and chars, also in course of high temperature chemical conversion.
