determination of sulphate as tio2 manufacturers
Chloride process. This process requires a high titanium feedstock. Rutile is reacted with hydrochloric acid to produce titanium tetrachloride, which can be hydrolyzed with steam or oxidized with air to render the dioxide. A rutile form of titanium dioxide is obtained.
Having thus descrihed my invention, I claim 1. Inthe production of a pigment the steps comprising slowly introducing titanium acid cake into a solution of barium sulphide while subjecting the mass to rapid agitation, mixing the resultant mass with a solution of zinc sulphate and separating the composite precipitate.
