| titleOfInvention | Making co-precipitated mixed oxide-treated titanium dioxide pigments |
| abstract | Simplified and improved processes are provided for manufacturing titanium dioxide pigments including a surface treatment whereby a plurality of inorganic oxides or a combination of one or more inorganic oxides with one or more inorganic phosphates are applied to a titanium dioxide base pigment. Aqueous acid-soluble sources of the desired inorganic oxides and/or phosphates are predissolved in an aqueous acid, and these can be added on a batch wise or more preferably on a continuous basis to an alkaline slurry containing the titanium dioxide base pigment and to which aqueous alkaline-soluble sources of the desired inorganic oxides are being or have been added previously. Co-precipitation of the oxides and/or oxides and phosphates is then accomplished by an adjustment of the pH, to provide a surface treated pigment with excellent homogeneity of the deposited mixed oxides and/or oxides and phosphates. |
