Abstract : The preparation of rare earth (RE)-Mn-amalgams, evaporation of mercury, preparation of mercuryfree alloys, and the examination of the alloys by metallographic and X-ray methods are described. Preparation of the RE (Y, Sm)-Mn-amalgams was simplified by developing a special method. Manganese metal, if pretreated in the right manner, can be dissolved simultaneously with the RE-metal in mercury, yielding directly the RE-Mn-amalgam (RE + Mn = approx. 1 wt-%). By this method pure amalgams, not contaminated by oxygen, can be produced in a reasonable time. (Author)
