6. Characterization of Coal by Dielectric Property : Evaluation of Thermal Behavior of Macromolecular Network Structure

Abstract

A new methodology for characterizing the thermal behavior of macromolecular network structure of coal has been developed by using the dielectric property measurement. It was found that the change of capacitance of solid coal demonstrated the characteristic pattern depending upon heating temperature, and from which the thermal property of polymeric substance such as glass transition, initial softening and fluid temperatures could be determined.
