HgTl Amalgam at 40% at. Tl: Eutectic at 1°C

Abstract

By means of a toroidal oscillating viscometer logarithmic decrements of dampings have been measured in presence or absence of HgTl amalgam at 40 atomic percent tallium at different temperatures, ranging from – 2°C to +15.625°C, with fluctuations every 0.25°C. Measurements were performed in two different periods (1:31/07/1990–21/12/1990 and 2:05/01/1991–09/05/1991). In both periods, the eutectic was found at 1.125°C.
