Orange pigments of inverse spinel structure produced by co- calcination of compounds of iron and zinc with compounds of titanium, tin and/or silicon

摘要

The present invention is directed to orange inorganic pigment materials which are characterized by high tinctorial strengths, excellent color and thermal stability and relatively high opacity. These pigments are of inverse spinel structure and are produced by cocalcining compounds of iron and zinc with compounds of titanium, tin and/or silicon.
