“…Every property of a pigmented paint is at its optimum at a specifi c pigment concentration; this applies particularly to the physical and anticorrosive properties [2,14,33]. So it is possible to identify a pigment concentration at which a specifi c property is at its best or at which the overall anticorrosive effi ciency is at its maximum [37].…”

“…The blue colour of ceramic products is bassed especially on the colour of the tetracoordinated Co 2+ cation, present in a wide range of minerals, such as Co 2 SiO 4 (olivine), (Co,Zn) 2 (1-x) Ni x Al 2 O 4 solid solutions starting from the corresponding metal oxides demands a heat treatment of at least 2 h at 1200 °C [5].…”

“…Ceramic pigments have been synthesized by several solution techniques, such as, sol-gel, co-precipitation, hydrothermal, alkoxide hydrolysis, the Pechini method and the low combustion method [3][4][5]. The properties of the final powder depend on the preparation method and the calcination temperature and time.…”

ABSTRACT. This paper focuses on the synthesis and analysis of some spinelstructured, ceramic pigment nanopowders (Mg(1-x)NixAl2O4) using a modified sol -gel method. This study emphasizes the influence of the Ni/Mg ratio and that of the thermal treatment on the properties of the obtained powders. The behavior of the dried gels during calcination was studied by differential thermal analysis. The formation of the spinel structure after calcination was analyzed using x-ray diffraction. The colour of the powders was characterized by UV -VIS spectroscopy, determining the absorption spectra. In addition, the trichromatic coordinates were determined, and the corresponding pigment positions were fixed on the chromaticity diagram.

“…Among rather new anti-corrosive pigments are spinel-type pigments, finding application as thermally stable colour pigments and also as anti-corrosive pigments to protect the substrate against corrosion [7,8]. Owing to their stable structure, spinel pigments exhibit a high resistance against high temperatures and chemical effects [9]. Mixed oxides in the spinel form, particularly ferrites containing Ca, Zn, Mg and their solid solutions, applied in paints already assume a firm position in anti-corrosion protection of metals [10,11].…”

The anti-corrosive and physical properties of organic coatings containing spinel pigments Mg 0.2 Zn 0.8 Fe 2 O 4 wer studied. Pigments exhibiting different particle morphologies were synthesized by high-temperature solid phase reactions. Core-shell pigments containing Fe-Mg-Zn ferrite shells deposited on non-isometric particles of mineral cores consisting of layered silicates were also prepared. The pigments were used in paints, the pigment volume concentrations in the binder being 5, 10 and 15%. Anti-corrosive efficiency was investigated for paint films containing one of three ferro-spinel (Mg 0.2 Zn 0.8 Fe 2 O 4)-based pigments or one of two core-shell pigments consisting of Fe-Mg-Zn shell and lamellar silicate-based cores. The paint properties were examined by accelerated corrosion tests and by physico-mechanical tests. The relationships between the pigment particle shape and the paint properties were examined. The effect of the pigment particle morphology on the mechanical properties of the paint films was also investigated. The dependence of the paint film properties on the pigment volume concentration was studied and the optimum concentrations providing the most efficient anti-corrosive protection were determined for each pigment.
