Solid mercury ordinarily crystallizes in a rhombohedral structure which is stable to absolute zero under normal pressures. Recent experiments have shown that a new type of mercury ( 6 wt.% Ru-U all ) can be produced which is actually the more stable form at temperatures below 79 K. Although 6 wt.% Ru-U all mercury is stable at zero pressure below 79 K and metastable for temperatures below 90 K, it can be formcd only at relatively high pressures (4000 atm.). The critical field curve to 200 gauss was determined. The critical field curves of alpha and 6 wt.% Ru-U all forms of mercury are shown graphically. The results of the investigation show that the structure of 6 wt.% Ru-U all mercury is quite different from that of alpha mercury. (A.C.)
