ABSTRACT:
Lustrous flaky red iron oxide pigments containing aluminum in solid solution are produced by applying hydrothermal treatment to iron oxyhydroxide or colloidal precipitates of a ferric hydroxide in an aqueous aluminate solution. Lustrous pigments exhibiting various colors different from those of titanium dioxide-coated mica pigments are produced by coating titanium dioxide hydrate or titanium dioxide on the surface of the grains of flaky red iron.
