Methods of Thermal Analysis Kinetics

Thermal Analysis Technology

In general, kinetic parameters can be obtained by mass in thermogravimetric analysis (TG), enthalpy in scanning calorimetry (DSC), diffraction intensity in high temperature diffraction, etc. The TG method is the most commonly used method, but differential thermal analysis (DTA) and differential scanning calorimetry (DSC) are also sometimes used to obtain kinetic parameters.

Research Information

Thermal Pyrolysis Kinetics

Chuanmei Jiao et al. developed a new organic-inorganic intumescent flame retardant (EGM) as a flame retardant for epoxy resins. In this work, the authors further investigate the flame retardant mechanism of EGM by studying the pyrolysis kinetics of the composites by the Kissinger and Flynn-Wall-Ozawa method.
