Fig. 4From: Applicability of carbothermic reduction for upgrading Sri Lankan ilmenite ores: towards converting ilmenite into synthetic rutile by mechanical activationX-ray diffraction patterns of ilmenite samples (a) annealed at 800 °C, (b) annealed at 900 °C, (c) annealed at 1000 °C, (d) annealed at 1100 °C, and (e) annealed at 1200 °C. Where, I: ilmenite (FeTiO3), R: rutile (TiO2), F: elemental iron. (see Table 1 for sample labelling)Back to article page
