| titleOfInvention | Titanium dioxide pigment and method of preparation |
| abstract | The present invention provides a pigmentary titanium composite having good durability and excellent optical properties. The inventive composite consists essentially of: a particulate titanium dioxide base; a hydrous zirconium oxide layer deposited on the titanium dioxide base ; and a hydrous alumina layer deposited on the hydrous zirconium oxide layer. The alumina layer consists essentially of boehmite alumina and/or pseudoboehmite alumina. The present invention also provides a method for preparing the inventive pigmentary composite. The inventive method comprises the steps of: (a) preparing an aqueous slurry comprising water and a particulate titanium dioxide base ; (b) depositing a layer of a hydrous zirconium oxide precipitate on the titanium dioxide base ; and (c) depositing a layer of a hydrous alumina precipitate on the layer of hydrous zirconium oxide. The hydrous alumina precipitate consists essentially of boehmite alumina and/or pseudoboehmite alumina. |
