(übersetzt):The thermodynamic and constitutional properties of Mg-Pd and Mg-Pt alloys were investigated. The partial Gibbs-enthalpies of Mg in Pd and Pt alloys with concentrations from 0 to 60 at.% Mg were measured in the temperature range from 1023 to 1073 K and 973 to 1073 K respectively using solid-state galvanic cells based on Fluorite as solid electrolyte. The existence of the phases Mg2Pd5, Mg3Pd5 and MgPd in the system Mg-Pd and MgPt7, MgPt3 and MgPt could be derived from the concentration dependence of activity. The existence of phases found by activity measurements was confirmed by the micro­probe investigations. A previously unknown phase in the system Mg-Pt was found at 60 at.% Mg.
