| 摘要 |
The invention relates to a method for doping, preferably coloring porous ceramics, particularly porous ceramic molds, wherein the ceramic is treated with at least one first suspension or solution containing metal ions and/or metal complexes. In at least one further (preferably subsequent) method step, the metal ions or metal complexes inserted into the ceramic preferably for coloring are immobilized by means of a second solution or suspension, preferably by at least one chemical precipitation reaction. The ceramic is preferably subjected to at least one heat treatment step / sintering step in a further method step. The invention further relates to a kit for doping, preferably coloring of porous ceramics, particularly of porous ceramic molds, comprising at least one first suspension or solution containing metal ions and/or metal complexes, and at least one second solution or suspensions for immobilizing the metal ions or metal complexes in the ceramic. |
