Abstract
The anticorrosion properties of paints containing mixed metal oxide-based pigments were examined. Spinels with the cation combinations Ti-Zn-Mg or Fe-Zn-Mg were synthesized. Core-shell pigments with zinc oxide and magnesium oxide layers were also prepared. The pigments were synthesized from the oxides or carbonates by the high-temperature solid-phase process. The anticorrosion and physico-mechanical properties of film of paints based on an alkyd resin modified with soy oil and containing the pigments at a volume concentration of 10% were investigated. The highest anticorrosion efficiency was observed with the ferrite-based pigments. The anticorrosion efficiency was found to increase with increasing Zn contents of the pigments.
