The chlorination of cerium dioxidewas studied by thermogravimetry under controlled atmosphere between 800 and 950 ◦C. An apparent activation energy of 190 kJ mol−1 was observed. To discriminate the effect of the vaporization of the CeCl3 on the chlorination rate, this processwas also studied with the same technique between 850 and 950 ◦C. An apparent activation energy of 184 kJ mol−1 was determined. The CeO2 chlorination rate was found to be under a chemical-mixed control influenced by the vaporization of CeCl3. © 2002 Elsevier Science B.V. All rights reserved. © 2002 Elsevier Science B.V.
