The work is devoted to a brief review of the few results available in the literature of an experimental study of the surface tension of liquid mercury in the region of negative temperatures adjacent to the melting point of mercury. It is shown that at present there is an acute shortage of reliable data on the surface tension of liquid mercury in the pre-crystallization temperature range, which are necessary for solving a number of problems that remain unanswered so far. The preliminary data of the authors on the temperature dependence of the surface tension of high-purity mercury in the range from +26 to –38°C (299–235 K), obtained by the large sessile drop method in a static vacuum of 10–4 Pa, are also presented. It is shown that the surface tension of high-purity mercury at a crystallization temperature 234.3 K (–38.8 °C) is 486.2 ± 3.5 mN/m, and in the studied temperature range, the surface tension polytherm is described by a straight line equation with a negative temperature coefficient dσ/dT = –0.287 mN/(m×Т). The results obtained in this work do not confirm the previously discovered L.L. Bircumshaw anomaly on the mercury surface tension polytherm in the form of a maximum at 238 K (–35 °C).
