Abstract: Process for preparing TiO2 powders starting from a liquid comprising chlorinated titanium compounds, the process comprising: a) atomizing said liquid and reacting the atomized liquid with a flow of steam and air at a temperature of 100-250° C. for converting said chlorinated titanium compounds to titanium dioxide TiO2; b) the gaseous phase and the entrained TiO2 powders obtained from step a) are then fed to an oven operated at a temperature in the range 400-900° C. to remove the residual organic compounds and hydrochloridic acid from said powders.
