摘    要:直接凝固注模成型是一种新型的陶瓷净尺寸胶态成型方法。综述直接凝固注模成型的研究状况,阐述直接凝固注模成型的基本原理、工艺流程和实施途径,重点总结3类典型的直接凝固注模成型体系,如酶催化体系、高价离子体系和有机物体系,并介绍该技术的后续处理工艺及应用,探讨直接凝固注模成型存在的主要问题及研究方向。

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.
