When subjected to ball milling Rutile, comprising additional impurities, was obtained as pure Rutile (without impurities) in smaller particle sizes. Anatas, which showed the same impurities, exhibited an elevated proportion of these impurities after grinding. Therefore TiO2 has only limited applications in high-energy ball milling experiments.
