Thermodynamic and Structural Properties of Metals and Alloys

Simultaneous measurements of the density and electrical conductivity have been carried out for expanded liquid Hg in the temperature and pressure range up to 1500°C and up to 2200 bar. At densities below 10 g/cm 3 the temperature coefficient of the conductivity at constant volume increases appreciably with decreasing density. Anomalous behaviours are found in the thermodynamic properties such as equation-of-state and isothermal compressibility when the metallic Hg is transformed to a nonmetallic state. Structural changes in the metal-nonmetal transition range are discussed in connection with the observed thermodynamic properties.
