摘　　要：综述了直接凝固注模成型技术的反应机理及其工艺流程,概括出悬浮体系凝固中影响凝固动力学的因素,并对当前国内外在该技术上的研究现状作了总结性介绍,讨论了直接凝固注模成型技术的主要研究问题及发展前景。The Direct Coagulation Casting (DCC) process offers the opportunity to produce the ceramic with complex shape and high strength. The process relies on electrostatic stabilized ceramic suspensions and its destabilization by time delayed in reactions. Enzyme catalyzed reactions may be used either to create salt at a constant pH or/and to shift the pH of the suspension to the isoelectric point of the powder. This paper summaries the main factors affecting DCC coagulation kinetics and some progresses of DCC process. Meanwhile, this paper also analyzes the major problems and development of DCC process in the future.
