【摘要】 介绍了Ｌａ２Ｏ３对还原钼粉粒度、形貌的影响，以及高温钼坯制取技术。结果表明：随着Ｌａ２Ｏ３含量的增加，钼粉粒度逐渐减小，颗粒形貌规则化。用掺Ｌａ２Ｏ３的钼粉与纯钼粉搭配后，可制取密度高，结晶细的坯料，且成品率较高更多还原

【Abstract】 The effect of La2O3 on the particle size and morphology of the reduced Mo powder, and a technique for producing hightemperature Mo blanks are introduced. The results show that with the increase of the content of La2O3, the particle size of the Mo powder gradually decreases and its shape becomes more regular. By blending La2O3doped Mo powder with pure Mo powder, Mo blanks with high density, grain size, and higher yield can be attained.更多还原
