Abstract
Coloring in a slip casting process by which a ceramic slurry is cast into green state bodies. It is during this slip casting that a coloring solution consisting of metallic salts is introduced to the slurry and subsequently slip-cast. A coloring solution may comprise for example a metallic salt, a solvent, an organic solvent such as derivatives of propylene oxides, and an acid can be introduced to the slip casting process. Such a coloring solution can be added to the slip casting process. The solution is thoroughly mixed with the ceramic slurry, after which the ceramic body is cast, dried and finally subjected to a sintering process. After final sinter, the resulting ceramic body possesses an innate color that is homogenous throughout its composition. The method is especially useful for coloring zirconia dental restorations.
