The pressed body consists of a single metal or of a plurality of metals forming a mixture or an alloy, the single metal or the mixture or alloy in turn not forming an alloy with mercury, being wettable by mercury and having a high oxidation resistance. The elements of subgroups 4 to 8 of the periodic table are particularly suitable as the single metal or as the main constituent of the mixture or alloy.
