A slip is a liquid mixture or slurry of clay and/or other materials suspended in water. It has many uses in the production of pottery, and other ceramic wares. In pottery the two most important uses of slip are: firstly, to form the basic shape by slipcasting with moulds; this has been extremely important for several centuries, and secondly, to protect or decorate the pottery, which is discussed below.
Method for coloring ceramics via colloidal dispersion
ActiveUS9365459B2Maintain colloidal stabilityFacilitate homogenous solutionImpression capsDentistry preparationsOrganic solventSlurry
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.

Process for manufacturing high density slip-cast fused silica bodies
ActiveUS20120098169A1Simple and cost-effectiveDrawback can be obviatedGlass shaping apparatusCeramic shaping apparatusVitrificationHigh density
Fused silica ceramics plays demanding role in high velocity missile / aircraft'radome development. Slip casting is the most common and commercially viable process utilized for radome production. Unfortunately slip casting cannot afford high density due to its poor green packing density which in turn results in poor rain erosion resistance. Present invention discloses process for preparing high density fused silica bodies by adding boron oxide (B2O3) with the commercially available high purity fused silica as sintering aid cum de-vitrification inhibitor. Various concentrations of B2O3 were added to high purity fused silica. Thus formed compositions were made into slip-castable slurries in aqueous medium without any addition of dispersing agents. The reheological properties like mild shear thinning and low thixotropic behaviour of the slurries were established. These slurries were then slip-casted in plaster of parries mold. The green and sintered properties of the casted samples were studied. The sintered sample with density higher than 2 g / cc (90-95% of the theoretical density) was achieved without de-vitrification. XRD studies on sintered samples showed the amorphous nature of the sample. The improved properties of fused silica system can favor its utilization in radome applications.
