An instrument that uses the gravimetric signal for performing Controlled Rate Thermal Analysis (CRTA) has been designed and used for the study of two high pressure reactions: the thermal oxidation of TiC under high pressure of oxygen and the reduction of Fe2O3 under high pressure of hydrogen.
Abstract
The potential of controlled rate thermal analysis (CRTA) for studying high‐pressure gas‐solid processes has been evaluated. CRTA is a type of smart temperature program based on a feedback system that uses any experimental signal related to the process evolution for commanding the temperature evolution. In this work, an instrument that uses the gravimetric signal for CRTA control has been designed and used for the study of two high‐pressure gas‐solid reactions: the highly exothermic thermal oxidation of TiC under high pressure of oxygen and the reduction in Fe2O3 under high pressure of hydrogen. Advantages of CRTA for discriminating overlapping processes and appraising kinetic reaction mechanisms are shown.
