The invention is concerned with the preparation of dispersions and particularly with the preparation of dispersions of cerium compounds. The invention provides for the preparation of an aqueous dispersion of ceria or hydrated ceria by a process which includes acid treatment of cerium IV hydroxide. Aqueous dispersions in accordance with the present invention find application in a number of technical fields (e.g. in the preparation of dense ceria coatings for use in catalysis and protective coatings, for example, for metals and alloys).
