Diamond-anvil system for the investigation of phase equilibria in mixtures at high pressures

Abstract

In order to investigate the phase behavior of mixtures at high pressures we have developed a system consisting of a diamond‐anvil cell with a high‐pressure vessel to match. The diamond cell can be filled at room temperature and pressures up to 10 kbar with a gaseous mixture of known composition. The cell is constructed such that a constant volume method can be used to measure the dew‐ and bubble‐point curves of a mixture.
