Enhanced sintering of molybdenum (Mo) powder through the addition of Ni and Zr was investigated. In order to obtain an uniform and fine dispertion of the additives on the surface of Mo particles, Ni and Zr were added using the nitrate solusions. The results obtained were as follows.<BR>(1) The densification of Mo powder during sintering was markedly enhanced through the additions of Zr in conjunction with Ni, whereas through the additions of Zr alone no such enhancement occured.<BR>(2) The sinterability of Mo powder increased with the increase of Ni.<BR>(3) The additives composed of Ni and Zr in a mass ratio of about 4 to 1 indicated the most enhancing effect on sintering of Mo powder. For instance, Mo powder contained 0.8mass%Ni and 0.2mass%Zr was densified to near the theoretical density by sintering at 1573K for 24ks.<BR>(4) In addition to sintering enhancement, Zr was very effective on the grain refinement of sintered Mo compacts.
