Abstract: In a method of coloring a ceramic material, a coloring solution consisting of metallic salts is introduced to a ceramic slurry. In a slip casting process, a coloring solution consisting of metallic salts is introduced to a ceramic slurry which is cast into green state bodies. A coloring solution that 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. In a method, the coloring solution is thoroughly mixed with the ceramic slurry, after which a 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 ceramic material used for making dental restorations.

Abstract: A colored ceramic powder is produced from a mixture of coloring solutions consisting of metallic salts that are introduced to a ceramic slurry and subsequently dried. The coloring solution may comprise for example of chosen metallic salts, a solvent, an organic solvent such as derivatives of propylene oxides, an acid and a possible binder. Once all the constituents are thoroughly mixed to a homogeneous state, the slip is dried to a powder form, which spray drying equipment can be used. The dried powder can then be subjected to an isostatic or biaxial press manufacturing process to create a green state ceramic body. Once pressed, the ceramic body can be 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.

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.

Abstract: A coloring liquid especially for shading pre-sintered ceramic dental restorations, utilizes a combination of metal salt, solvent and acid to achieve natural tooth coloring of standard dental shades. By adjusting the respective ingredients, different shades can be provided and color penetration can be sufficient to preserve aesthetics in the sintered restoration even when some of the ceramic material is removed.
