Abstract:Direct coagulation casting (DCC) is a novel near-net-shape colloidal processing of ceramics. The research and development of direct coagulation casting was reviewed. The fundamental theory, technology process and implement approaches of this ceramic forming technique were elaborated. In addition, three kinds of typical coagulation systems including enzyme catalysis, high valence counter-ion and organic system were summarized. Furthermore, the post-processing technique and the application were introduced. Finally, the problems and development of direct coagulation casting were also discussed.
Key words: ceramics; direct coagulation casting; coagulation system; post-processing technique
