稀土对MoSi_2低温氧化行为的影响

EFFECTS OF RARE-EARTH ELEMENT ON LOW-TEMPERATURE OXIDATION PROCESS OF MoSi 2

利用热重量分析法（简称ＴＧＡ法）、Ｘ－射线衍射（Ｘ－Ｒａｙ）和扫描电镜观察（ＳＥＭ）分析了稀土在ＭｏＳｉ２低温下氧化中的作用。结果表明，稀土的加入促进了ＭｏＳｉ２的氧化程度，但未发现“ＰＥＳＴ”现象。

The effects of rare earth element on low temperature oxidation of MoSi 2 have been analyzed by TGA,X ray and SEM.The degree of oxidation of MoSi 2 has been increased by adding rare earth element,but“PEST” has not been found.
