The study of phase equilibria at elevated temperature and pressure using a sapphire reactor gets a new quality of visual control. Of course, the traditionally used methods of working with thin-walled capillaries make it possible to observe the behavior of phase boundaries, but working with dispersed systems and solid phases is very difficult. The system Comvics team developed for us allows not only to see all the processes of phase transformation, but also to carry out sampling of any phase and to control this process. Visual control in a sapphire reactor opens up new horizons for conducting experiments. The use of spectral methods for phase analysis became possible with the passage of the phase boundary with a large absorbing layer.
