TiO 2 + C + 2Cl 2 → TiCl 4 + CO 2. The TiCl 4 is recovered and then distilled to generate purified TiCl 4. This is then reoxidized to pure TiO 2 using oxygen gas. The chlorine gas generated in the reoxidation step is recovered and re-used in the process. The fine-particle size TiO 2 product typically undergoes milling, and small amounts of ...
