| Abstract | A computer-monitoring thermogravimetric system was used to study the effect of alkali chlorides(MCl, M = Li, Na, K and Cs) on the carbothermic reduction of pre-oxidized ilmenite in the course of a linear rise in temperature from 600 degreesC to 1000 degreesC. The experimental results indicate that all the alkali chlorides can speed up the reduction process of preoxidized ilmenite, moreover, KCl is the most effective catalyst of the chlorides, while the catalytic effects of LiCl and CsCl are relatively weaker. It seems that the catalytic mechanism of LiCl is different from those of the other alkali chlorides. The cross-sectional morphology of the partially reduced pre-oxidized ilmenite particles and the distribution of potassium ions within them were examined by means of scanning electronic microscopy and electronic probe microanalysis, respectively, which shows that the reduction proceeds topochemically and the alkali ion enriches at the periphery of the particles. |
