The reactivity of the anode and its constituents was assessed separately and their effect on dusting phenomenon was discussed. real density, crystallite size and specific surface area, were measured. The microstructural features of the samples, i.e. The air and CO 2 reactivities were evaluated using thermo-gravimetric analysis and the standard reactivity test of R&D Carbon, ISO Standard 12981-1. The present work aims at elucidating this phenomenon by studying the air and CO 2 reactivities of the prebaked carbon anode and also of its constituents. More precisely, it is believed that CO 2 and O 2 preferentially attack the baked pitch (pitch coke) resulting in detachment of coke and butt particles in the form of dust. These reactions are considered as being the main causes of dusting phenomenon in the electrolysis bath. Carbon anode, used in the Hall-Héroult process, is subject to both air oxidation and carboxy gasification by CO 2.
