FIELD: industrial inorganic synthesis.
SUBSTANCE: invention relates to a sulfate process for titanium dioxide production from titanium-containing material. Process comprises leaching starting material to produce leaching lye containing acidic solution of titanyl sulfate, which is separated from the lye and then hydrolyzed to form hydrated titanium oxides further fired to produce desired titanium dioxide. Hydrolysis step is properly controlled to form hydrated titanium oxides with desired particle size distribution.
EFFECT: enhanced commercial process efficiency.
