| 20140109797 | Method For Manufacturing Coloring Ceramics Via Colloidal Dispersion Followed By Conventional Pressing Techniques - 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. | 04-24-2014 |
