Anticorrosive spinel‐type pigments of the mixed metal oxides compared to metal polyphosphates

Abstract

The spinel‐type pigments of a general formula corresponding to AB₂O₄ containing as A the Mg²⁺ or Zn²⁺ ions and as B the Fe³⁺ or Al³⁺ ions or combinations of both the A and B were prepared and investigated with respect to their anticorrosive action as pigments in organic coatings. For the same purposes, comparative pigments, known for their efficiency as the metal‐corrosion inhibiting ingredients in similar formulations, were used. Further evaluation was carried out on the properties of condensed phosphates as anticorrosion pigments. The results obtained showed the high anticorrosion action of the spinel‐type pigments.
