    摘要: Anticorrosive white pigments useful for inhibiting corrosion include surface-coated TiO2 base bodies, preferably in the rutile modification, having Mn3(PO4)2 and one or more of the substances chosen from aluminum oxides, aluminum hydroxides, aluminum phosphates, aluminum hydrogen phosphates, aluminum dihydrogen phosphates and aluminum polyphosphates are precipitated on to the TiO2 base bodies. Mn3(PO4)2 may be replaced completely or partially by Zn3(PO4)2. Phosphates and/or oxides of cerium may be additionally deposited singly, or several of them may be deposited, on to the TiO2 base bodies.

    摘要: Inorganic anti-corrosive pigments consist of surface-coated solids having a grain size of 0.1 to 75 &mgr;m. In order to improve the resistance of the paints and coatings containing such pigments, firstly Mn3(PO4)2 and secondly aluminium oxides and/or aluminium hydroxides are precipitated onto the solids.
