ABSTRACT OF THE DISCLOSURE PREPARATION OF ANATASE TITANIUM DIOXIDE A process for the preparation of anatase titanium dioxide having a high surface area and suitable as a catalyst support is described. The process involves forming an aqueous dispersion of titanium dioxide at pH less than 3 and preferably less than 1 and depositing a first coating of a hydrous oxide of an element which acts as a rutilisation inhibitor and a second coating of a phosphate on the particles of titanium dioxide. The product of the process has a high surface area which is retained on heating for long periods at high temperature. A novel product is particulate anatase titanium dioxide which has been coated with a rutile inhibitor and a phosphate, has a specific surface area of at least 50 m2/g and retains at least 80% of its surface area after heating at 800°C for 7 days.
