A phase equilibrium study of the mercury--mercuric chloride system was carried out by thermal analysis and by the visual method. Yhe salt-rich eutectic composition is 4.9 mole% Hg and occurs at 273 tained . The syntectic line at 525 tained extends from 48 to 94 mole% Hg. The solubility of HgCl/sub 2/ in Hg increases to 6.8 mole% at 560 tained . Freezing point depression measurements for HgCl/sub 2/ suggest that Hg dissolves either as atoms or as Hg/sub 2/Cl/sub 2/ molecules formed by reaction of RO with HgCl/sub 2/. A thermcdynamic analysis of the liquid-solid equilibrium curve between the salt- rich eutectic and the base of the miscibility gap suggests that solution of Hg as atoms is not likely in this region.
