| Abstract: | The relationship between oxygen potential within rich titaniumbearing slag and time was obtained by oxygen sensor of solid electrolyte at the designed temperatures (1713, 1723, 1733 and 1743 K)in the air, and the kinetics equation for the oxidation of (TiO1.5) was put forward. The effects of iron oede added in slag at different levels on the oxidizing rate were also discussed. Besides, the Arrhenius activation energy of oxygen diffusion in slag and its diffusion coefficient were obtained at the givn conditions. |
