Three processes of Colloid Casting including Slip Casting, Centrifugal Casting, and Gel Casting

Recent works demonstrated that the Creditability of ceramic materials can be modified by using colloidal processing methods.

Recent works demonstrated that the Creditability of ceramic materials can be modified by using colloidal processing methods. In a new research study, colloid-casting processes like slip casting, pressure casting, vacuum casting, centrifugal casting, and gel casting for manufacture of complex shaped components with microstructural homogeneity are examined deeply and carefully. These tracks can make production of green bodies directly from suspension.

The first critical stage of such processes is to get well-dispersed, uniform, and concentrated slip with related sintering additives to achieve stable slips and homogenous ceramic shapes. In addition, casting-forming kinetics is the most important factor to manufacture complex ceramic shapes in an economically valid behavior. Slip casting is one of the most broadly used industrial method for production of ceramic components based on removal of the water in the slurry by capillary action until a thick layer (desired shape) is formed along the porous mold. Pressure, vacuum, and centrifugal casting are more currently used to shorten the casting time and drying time of the molds, so long as preparing more chances for automation. At the end, in gel casting green bodies are produced through in situ polymerization of a slurry compromised of ceramic powders and organic monomers to produce a macromolecular network for holding the ceramic particles together in the desired shape.
