Abstract

A suspension of titania in a gas, e.g. titanium dioxide produced in vapour phase oxidation of titanium tetrachloride, is cooled from a high temperature, such as would exist in the vapour phase oxidation at 850 DEG -1350 DEG C., to a relatively lower temperature, about 600 DEG C., by passing the gaseous suspension through an externally cooled conduit which is preferably corrosion resistant, characterized in that an inert solid of particles larger than the suspended solids, which may have been cooled, is mixed with the suspension and the rate of flow is maintained so that the titania does not stick to the internal walls of the conduit.
