Abstract

Process for the preparation of a titanium dioxide pigment with improved stability against climatic conditions by means of a further treatment which is carried out by mixing a pigment of titanium dioxide prepared in any way in aqueous suspension with water-soluble salts of aluminum and zirconium and optionally one or more other water-soluble metal salts which, in the neutralization, form non-colored and hardly soluble hydrous oxides or other types of uncoloured and hardly soluble compounds and/or optionally a water-soluble silicate, adding to the mixture, if necessary, in the case of an acid reaction of the suspension, a substance with an alkaline reaction or a mixture of substances with an alkaline reaction until at least neutral reaction, and in the case of an alkaline reaction of the suspension, on the other hand, a substance with an acid reaction or a mixture of substances with acid reaction until at least neutral reaction, and filtering, washing, drying and grinding the pigment thus treated, characterized in that the zirconium salt is added before the remaining substances and the zirconium is precipitated on the surface of the pigment of titanium dioxide in the form of at least partially hydrated zirconium dioxide before the precipitation of other hydrated oxides and/or other hardly soluble compounds.
