“…A metal-non-metal transition represented by drastic decrease of electrical conductivity in the vicinity of a critical point has been reported earlier in liquid Cs [11,12], Hg [13,14], and Se [15,16]. The phenomenon in Cs and Hg was explained as a result of a permanent reduction in the density by factor of 2.…”

“…The main body (1) machined from forged molybdenum has a cyli~drical hole of 170 mm length and 3 mm diameter and is closed at one end. It incorporates two concentric tubes of sintered, pure and nonporous alumina (2), (3) which both lead out of the cell into a cold closure where teflon can be used for sealing and insulation. The closure consists of three separate sections.…”

The absolute thermoelectric power of liquid and supercritical mercury has been measured between 600°C and 1700°C at pressures up to 3300 bar. For that purpose a cell of forged molybdenum and pure sintered alumina was developed which allows the simultaneous measurement of the thermoelectric power S and the electrical conductivity σ of liquid and gaseous mercury. The measurements were performed in an internally heated high pressure vessel.A strong density dependence of S and σ is observed. If the mercury density is decreased from 12 g/cm3 to 5 g/cm3, S varies continuously from ‐ 23 μV/deg to ‐ 550μV/deg indicating a gradual transition from a metallic to a nonmetallic state. It is proposed that a pseudogap is formed in expanded mercury and that the states in the pseudogap become localized for densities smaller than 9 g/cm3. For densities smaller than this σ and S are consistent with excitation of electrons from localized states at the fermi energy to extended states at the mobility edge.
