Abstract

In order to study phase equilibria in aqueous systems at high temperatures, a diamond-anvil cell that can be loaded with compressed-gas mixtures and a matching thermostat were developed. Care was taken to ensure a stable (0.1 K) and homogeneous (<0.5 K) temperature distribution inside the cell by using a two-stage heating system. Experiments were performed up to 50 kbar at 650 K on pure nitrogen. The observed melting line of nitrogen is in very good agreement with previous results.
