Abstract : Compounds of samarium, gadolinium and yttrium with mercury were prepared by direct reaction between the RE-metals and mercury vapor at temperatures between 200 - 500 C. The RE-metals form compounds of the formulas ReHg, ReHg2 and ReHg3. The respective Sm compounds fit to the data, which have been given earlier. The Gd and Y compounds were prepared and studied for the first time. Their structures and lattice spacings were evaluated and are very similar. A furnace suitable for the preparation of RE-metals and alloys from the amalgams at higher temperatures is described. The obtained RE-metals are practically free of mercury and have the same structures and lattice spacings as well annealed metals, obtained by fusion. (Author)
