✦ Synopsis

Invited paper

Recently we have developed a diamond-anvil system for the investigation of phase equilibria in gaseous mixtures up to 100 kbar. The phase behaviour of binary systems at high pressures will be discussed and some experimental results will be presented for the systems neon-xenon and helium-hydrogen. It turns out that the three phase line and the critical line diverge for the system He-H 2 even at a pressure of 60 kbar, so that fluid-fluid equilibrium will persist up to very high pressures.
