ABSTRACT:
Small quantities of an alkali metal salt control additive, along with the addition of a rutile promotion additive, preferably aluminum trichloride as ruffle promoter, is added in the oxidation of titanium tetrachloride into the titanium dioxide burner reaction zone. Metal used to make aluminum trichloride is introduced into a aluminum chloride generator reactor in a main branch, and the alkali metal salt is introduced in a subsidiary branch in a controlled addition provided by a "dilution" mixture of the salt in aluminum powder and preferably by applying additional agents which improve the flee-flowing properties of the mixture such as, for example, anhydrous potassium oleate.
