Resumen:
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.◦C.
