介绍了Ｌａ２Ｏ３对还原钼粉形貌和粒度的影响，以及Ｌａ２Ｏ３对钼粉制坯的影响。简述了Ｌａ２Ｏ３的一些特性，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；市购氧化镧加入钼粉中，需进行还原处理，才能进行制坯。
The effects of La2O3 on morphology and particle size of reduced molybdenum powder and the effect of La2O3 on the molybdenum powder billet were introduced. Some properties of La2O3 are briefly described. The results show that with the increase of La2O3 content, the particle size of molybdenum powder gradually decreases and the morphology of the particles is regularized. When lanthanum oxide is added into the molybdenum powder, it needs to be reduced to make it.
