Resumen:
The two
reaction stages of the carbochlorination of ZrO2 that we have
recently reported were investigated by thermogravimetric measurements and
characterized by following the morphological evolution of the solids by
scanning electronic microscopy (SEM).
Chlorine atoms are proposed as reaction
intermediates in both reaction stages. Evidence of a catalytic-like action of
carbon by the dissociation of chlorine gas is observed in the initial stage,
and the occurrence of the O2-C reaction is inferred in the second
stage.
