A SINTER PROCESS, USING MERCURY AS AN 'AUXILIARY COMPONENT' AS APPLIED TO RE-MN SYSTEMS. (A SUMMARIZING DISCUSSION). DIFFERENTIAL-THERMAL- AND MAGNETO-THERMALANALYSIS OF THE SYSTEM GD-MN (0 - 50 W.% MN),
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.
