The Effect of Titanium on Reduction .
The effect of titanium oxide in solid solution in magnetite on the magnetite to haematite transformation rate was studied first in order to simulate the final stage of the sintering process. In other experiments, haematite samples doped with, and wt per cent titanium oxide were studied using thermogravimetry under a controlled gas atmosphere (CO/CO 2 /H 2 /N 2 ).
