摘　　要：陶瓷的胶态注射成型工艺适应了高性能陶瓷产业化的需要 ,其关键是要通过制备均匀性好的陶瓷坯体而保证部件的使用可靠性。本文提出在胶态注射成型液固转变过程中容易产生内应力 ,并且初步研究了陶瓷坯体中内应力的产生、遗传和变异的规律 。The preparation of homogeneous green body during colloidal injection moulding is a key step to improve the reliability of ceramic parts in order to satisfy the need of industrialization of high performance ceramics. In this paper, it is poi nted out that internal stress is produced easily during liquid-solid conversion of colloidal injection moulding. The generation and inheritance and aberrance o f internal stress are discussed primarily. Finally, a way to release internal str ess is put forward.
