摘　　要：MoSi2是一种重要的用于制造高温发热元件的材料和航空航天用高温结构材料。比较了MoSi2的几种制备方法:机械合金化、自蔓延高温合成、热等静压法、固态置换反应和原位反应自生复合技术等。结果表明:为实现MoSi2材料的产业化,应采用原位反应热压制备工艺。评述了MoSi2及其复合材料的工业应用情况,提出了其未来研究发展的方向。MoSi2 is one of the important high temperature heating element materials and structural materials for aerospace application. Several preparation methods were compared and studied ,such as mechanical alloying , selfpropagating high-temperature synthesis, hot isostatic pressing, solid state displacement reaction and in-situ reaction synthesis. The results of research show that in order to realize industrialization of MoSi2 materials, preparation technology of in-situ reaction hot-pressing should be adopted. The status of industrial application of MoSi2 and it ＇s composites was reviewed. The direction of research and development for future was put forward.
