Summary: | A zinc ferrite pigment comprising, by weight, about 99.8 to 90% of ZnFe2O4 and about 0.2 to 10% of the component system (1-x)Al2O3 and xP2O5 wherein 0<x<1 is produced by calcining a suitable mixture of compounds. The resulting pigments are of high color quality and are substantially halogen-free, rendering them especially useful industrially even as anti-corrosion pigments. |
