In this present study, the effects of mechanical activation on the characterization of titania slag were systematically investigated. The crystal structures, surface chemical functional groups, and microstructure of the samples were characterized before and after mechanical activation using XRD, FT-IR, and Raman spectroscopy techniques, respectively. It was found that untreated titania slag under mechanical activation was mainly composed of Fe3Ti3O10 and rutile TiO2, but that of being treated by mechanical activation was mainly composed of Fe 3Ti3O10, Ti2O3 and rutile TiO2. Ti2O3 is transformed partially from Fe3Ti3O10 under moderate mechanical activation conditions for 12 h. The demonstration of mechanical activation techniques can be applied effectively and efficiently to the treatment processing of titania slag.
