摘　　要：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。This study gives an introduction to the effect of La 2O 3 on its shape and size after reduction and also that of La 2O 3 on the blank making of Mo Powder.It briefly introduces the characters of La 2O 3.The result indicates:With the increase of the content of La 2O 3,the size of Mo powder gradually reduction,the shape of Mo Powder becomes regular.If the Lanthana got from the market is added to Mo powder ,reduction is needed before making blanks.
