Abstract:

Advanced structural ceramics possess excellent properties such as high-temperature resistance and play an irreplaceable and important role in national defence and economic development. Brittleness is the main bottleneck restricting the development of ceramic materials. The emergence of plastic ceramics brings new hope for overcoming the brittleness of ceramics, which has important scientific significance and application value. In recent years, Chinese scholars have made breakthrough progress in the field of plastic ceramics, sparking a worldwide upsurge in the study of plastic ceramics. China should seize this chance, develop a timely layout, and promote the basic and applied research of plastic ceramics, so as to take a leading position in global science and technology competition of this field and provide strong support for meeting major needs such as aircraft engines.

Key words: plastic ceramics, plasticity at room temperature, silicon nitride, aero engines

摘要：

先进结构陶瓷具有耐高温等优异性能，在国防和国民经济建设中发挥着不可替代的重要作用。脆性是制约陶瓷材料发展的主要瓶颈，塑性陶瓷的出现为克服陶瓷脆性带来新的希望，具有重要的科学意义和应用价值。近年来，中国学者率先在塑性陶瓷研究中取得突破，在世界范围内掀起塑性陶瓷研究热潮。中国应充分抓住先发优势，及时布局，大力推进塑性陶瓷基础与应用研究，在该领域的全球科技竞争中占据领先地位，为满足航空发动机等重大需求提供有力支撑。
