Brown pigments synthesized with obtaining simple spinels Mg[Fe2]O4, Zn[Fe2]O4 and mixed spinel (Zn, Mg)[Fe2]O4.When using metal hydroxides, especially precipitators that may have an increased reaction capacity, brown pigment synthesis is the reaction: Zn(OH)2 + Fe(OH)3 = Zn(x-1)Fey[ZnxFe(2-y)]O4 + 3H2O. popup.nrat_date 2025-05-13 Close
