PRODUCTION OF TITANIUM CHLORIDES

摘要

Titanium dichloride and or titanium trichloride is produced directly from a titaniferous ore such as ilmenite by means of a selective chlorination reaction. A mixture of particles of the ore and particles of carbon is contacted at a temperature greater than 1500 DEG C with a quantity of chlorine less than that required in theory for the production of titanium tetrachloride, for example, from 0.75 to 1.75 moles of chlorine per mole of titanium dioxide. Provided a sufficient quantity of carbon is used the iron content of the ore may be converted into the metallic form and recovered as such. The titanium chlorides produced may be further chlorinated to titanium tetrachloride.
