Abstract (en)
[origin: DE19841318A1] Ceramic surfaces are colored by forming a mixed phase pigment made of a colorless metal oxide as matrix lattice consisting of a different crystal lattice structure than the colored pigment, and an aqueous coloring solution in the surface of a ceramic body. Process for coloring ceramic surfaces comprises forming in the surface of a ceramic body a mixed phase pigment made of a colorless metal oxide as matrix lattice consisting of a different crystal lattice structure than the colored pigment, and an aqueous coloring solution by either incorporating the finely divided colorless oxide into the ceramic composition and applying the colored solution to the surface layer, or by reacting the aqueous coloring solution with a soluble compound of the metal ions forming the lattice in a sufficient amount to form the lattice, and applying this mixture to the surface, or applying a solution of the metal ions forming the lattice and followed by the coloring solution and firing the ceramic body at 800-1400 deg C after drying the solvent.
