    摘要: A method for producing titanium dioxide with an anatase crystal structure from a titanium oxychloride solution. Titanium tetrachloride is mixed with water to form titanium oxychloride, which in turn is mixed with an organic reagent, preferably sorbitol. The resulting solution is hydrolyzed, precipitated and calcined to form titanium dioxide with an anatase crystal structure.

    摘要: A titanium dioxide compositon suitable for incorporation into ceramic frit, and process for preparation thereof. A clarified titanium sulfate liquor is hydrolyzed and precipitated to yield relatively large and uniform-sized hydrolysate particles which are easily separated from the acidic liquor by filtration.

    摘要: A titanium oxide hydrolysate slurry prepared by the sulfate process is treated with either an alkali metal hydroxide or an alkali metal carbonate to solubilize the sulfur bound to the titanium at a temperature of from 60.degree. C. to 120.degree. C. and the slurry is treated with an organic acid to remove the alkali metal compounds present. This process produces titanium oxide hydrolysate of high purity.
