Abstract
The effect of the type of carbon on β- Ta2O5 chlorination with Cl2-Ar and Cl2-Ar-O2 gas mixtures was studied by isothermal and non-isothermal thermogravimetric measurements. The carbons used were carbon black, sucrose carbon and graphite and the characterization techniques were BET area, scanning electron microscopy (SEM) and X-ray diffraction (XRD). It was observed that the carbochlorination reaction reactivity increased with higher carbon percentages. On the other hand, the carbochlorination reaction was favoured both chemically and kinetically by the carbon with the highest reducing activity according to the following reactivity order: carbon black > sucrose carbon > graphite.On a fait des recherches à propos de l’effet du type de charbon sur la chloration de β- Ta2O5 avec des mélanges gazeux de Cl2-Ar et Cl2-Ar-O2, en faisant des mesures thermogravimétriques isothermiques et non isothermiques. Les charbons utilisés ont été carbon black, surcrose carbon et graphite. Les techniques de caractérisation utilisées ont été BET, microscopie électronique de balayage (SEM) et diffraction de rayons X (XRD). On a observé qu’un accroissement dans le pourcentage de charbon augmente la réactivité de la réaction de carbochloration. D’autre part, la réaction de carbochloration est favorisée chimiquement et cinétiquement par le charbon plus réducteur, selon l’ordre suivant de réactivité: carbon black > surcrose carbon > graphite.
