Abstract
Coated particles having properties such as to make them suitable as replacements for titanium dioxide particles can be obtained by reacting a titanium or zirconium halide, ether, or ester with zeolite hydrate particles so as to coat the zeolite particles with titania or zirconia. The reaction is preferably conducted between a titanium compound, such as titanium tetrachloride, and the zeolite in an inert medium, such as anhydrous or substantially anhydrous air or a hydrocarbon.
