Abstract   Slip casting and injection molding are the most common methods used to mass fabricate complex-shaped ceramic parts. Both methods induce imperfections in the green part, which lead to inhomogeneous microstructures in the sintered parts. In view of this, a new fabrication method called direct coagulation casting (DCC) has been developed. This method has a potential for the mass production of complex ceramic parts with high strength and reliability. In DCC, an aqueous suspension is coagulated by a change in pH or an increase in ionic strength after casting thereby producing a rigid green body. By using DCC, most of the limitations of conventional shaping techniques are avoided. [46 Refs; In English]
