Abstract:

A summarizing discussion of the amalgam process is given which turned out to lead to equilibrium states even at higher temperatures than 300 - 400 C. Applying the amalgam process to higher temperatures 800 - 1200 C the mercury, bound by the respective RE-metals, plays the role of an auxiliary component. The amalgam process is the main step of a very particular sinter process. The distillation of mercury out of the amalgam yields intimately mixtures of very fine and reactive powders of RE- and Mn-metal. The different steps of the sinter process are described in detail as well as the results gained applying this alloying method to the RE Gd, Sm, Dy, Ho, Er-Mn systems. By means of newly developed methods for differential thermal analysis DTA and magnetothermal analysis of small amounts of high reactive materials, especially the system Gd-Mn was studied and a partial phase diagram 0 - 50 w. Gd is given.
