Abstract
The invention relates to manufacturing titanium dioxide by oxidizing titanium tetrachloride by a multi-stage method, where liquid titanium tetrachloride is used in a first and gaseous titanium tetrachloride is used in a second stage. The process is energetically more favorable and offers the possibility, to a certain extent, of controlling the mean particle size of the end product.
