Research and Development of High Performance Ceramics With Structural and Functional Properties Combined

从当前新材料的开发和材料科学发展向多功能、小型化、复合化、低成本制备等要求出发 ,并就现有高性能陶瓷材料的基本性能和材料制备工艺上的优缺点进行了分析 ;简要介绍了碳化硅 (SiC)陶瓷、添加Nd的钇铝石榴子石 (Nd -YAG)陶瓷、掺有稀土的氮化硅 (RE -Si3 N4)陶瓷等几种具有结构和功能一体化高性能陶瓷材料的优良性能 ,可能的应用以及目前存在的问题 。

This paper introduces some developing trends of new materials and material sciences, such as multifunction, composite, miniat urization, low cost manufacturing and analyses the basic properties and pro blems of processing of hig h performance ceramics nowadays. The paper briefly describes some special pr operties, possible application fields and mass production problems of ceramics with structural and functional properties combined,such as silicon carbide, Nd doped YAG, and Sialon with rare\|earth elements added. Finally, proposed several topics (including processing sciences)of such kind o f multi function materials for future research and developing.
