Abstract

See full text

Plateletlike titanium dioxide reduction pigment consisting of titanium dioxide, titanium suboxides and, if desired, a further metal oxide or titanium oxynitride, obtainable by solidifying an aqueous solution of a thermally hydrolysable titanium compound on a continuous belt, detaching the resulting coat, coating the resulting titanium dioxide platelets, with or without drying in between, with further titanium dioxide by a wet method, drying and, if desired, calcining the material, and treating the material obtained with a reducing agent in a nonoxidizing gas atmosphere.
