- Abstract
The titanium dioxide(TiO2) was prepared by efficient decomposition of titanium- bearing blast furnace slag (TBBFS) in molten salt system. The as-prepared TiO2 were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Almost complete leaching of Ti was achieved when TBBFS was carried out at 500 °C for about 3 h with NaOH/TBBFS mass ratio of 3:1 and NaOH to NaF molar ratio of 3:1. The XRD pattern showed that the containing titanium product obtained under optimal conditions was Na2 TiO3. The average size of the rutile TiO2 obtained was about 1.0μm and the content was up to 99,23 %.
