Metal-Nonmetal Transition in Dense Mercury Vapor

摘要: This article presents the results of conductivity and density measurements liquid, gaseous, supercritical mercury up to 1700\ifmmode^\circ\else\textdegree\fi{}C 2100 bar. Beyond critical temperature 1490\ifmmode^\circ\else\textdegree\fi{}C varies continuously from ${10}^{\ensuremath{-}4}$ ${10}^{2}$ ${\mathrm{\ensuremath{\Omega}}}^{\ensuremath{-}1}$ ${\mathrm{cm}}^{\ensuremath{-}1}$ if is increased 2 6 g/${\mathrm{cm}}^{3}$. variation an example nonmetal-metal transition discussed accordingly. The activation energy in fluid decreases markedly with increasing approaches very small values around 5 Conductivity data for dense gaseous mercurycesium mixtures are given.
