| abstract | 1365411 Coated TiO2 BRITISH TITAN Ltd 26 Feb 1973 [23 March 1972] 13724/72 Heading C1N Coated TiO2 is produced by forming a suspension or slurry of TiO2 containing a water-soluble silicate, adding an acidic hydrolysable Al compound while maintaining the pH at 3-4À5 to precipitate hydrous SiO2, and raising the pH to precipitate hydrous Al2O3. The pH of the silicate-containing suspension may initially be adjusted with acid, e.g. H2SO4 or HCl. The Al compound may be Al2(SO4)3, Al(NO3)3 or AlCl3, and may be added simultaneously with alkali, e.g. NaOH or further silicate, to maintain the pH. Alternatively, the alkali may first be added to the Al salt until precipitation is about to occur, e.g. NaOH may be added to AlCl3 until the OH/Al ratio is 2À2. Phosphate ions may be added after the Al compound, e.g. as NaH2PO4 or H3PO4. A further coating may be provided by adding a compound of Al, Ti, Ce, Zn, Zr or Si and adjusting the pH to effect precipitation. The TiO2 may be anatase or rutile, average size 0À15-0À3 Á, obtained by the sulphate or chloride process. The silicate may be Na or K silicate. |
