摘要
ＭＯ、Ｗ、Ｓｉ粉未通过自蔓延燃烧合成ＷＳｉ２－ＭＯＳｉ２复合材料，粉末Ｗ量影响合成反应。ＭＯ：Ｗ原子比≤１，合成反应不能进行。合成产物相ＷＳｉ２、ＭＯＳｉ２实际上是以固溶体（ＷｘＭｏｙ）Ｓｉ２形式存在，并且合成伴生少量（ＷｘＭｏｙ）５Ｓｉ３．
the synthesis of WSi 2-W OSi 2 made from W、M O,and Si powers by self-propagating combustion method is investigated, it is found whether reaction can happen is determined by W atom amount When the atom ratio of M O:W was lower than 1,the synthesis reaction could nkt happen. The csact form of synthesis productions Wsi 2 and W OSi 2 is predominently solid solutions (W xMo y)Si 2,companided by small fractioon of (W xMo y) 5Si 3 phase.
