Abstract
Titanium dioxide particles are coated first with an interstitial coating and then with silicon dioxide or alumina. The coatings are suitably applied via an atomic layer deposition process. The interstitial coating preserves the bright white coloration of the particles after they are coated. The particles therefore can be used as pigments and white fillers in polymers, paints, paper and other applications.
