Study of brine-halite phase separation through optical constringence and molecular dynamics
VM Lenart and LS de Lara and SL Gomez and RF Turchiello, EUROPEAN PHYSICAL JOURNAL E, 45, 57 (2022).
This work presents a study of the reciprocal dispersive power, also known as constringence or Abbe number of an aqueous solution of NaCl in a wide range of concentrations. The constringence exhibited a distinct behavior in the region close to the phase transition between a phase containing exclusively brine and a phase containing brine+halite. Molecular dynamics simulations of this system indicated the existence of halite formation below the known saturation curve, which agreed with the experimental measurements, indicating a crystal growth in the unsaturated region.
