High Hydrogen Pressures in Superconductivity

  • B. Baranowski
  • T. Skoskiewicz


The experimental conditions for the preparation of metallic hydrogen are not easily available. Therefore it is of interest to study the eventual metallic behaviour of hydrogen in the form of its alloys1 as these can be probably obtained in much less extremal conditions than the pure component. This means —first of all—a much smaller equilibrium pressure of hydrogen above such alloys than is the case for metallic hydrogen. Let us stress here the analogy to metallic mercury whose equilibrium pressure above amalgams can be by orders of magnitude smaller than above the pure component. It is obvious that the higher the thermodynamic activity of hydrogen the closer the approach to its eventual metallic behaviour.
