In Situ Investigation of the Mechanism of BaO Dissolution in Chloride Melts by Raman Spectroscopy

  • Published:
Journal of Applied Spectroscopy Aims and scope

The mechanism of BaO dissolution in a melt of the BaCl2–KCl–NaCl eutectic mixture was determined in situ using Raman spectroscopy. The types, structures, and compositions of oxychloride groups present in the melt were established. It was found that BaO dissolution proceeded according to the reaction BaO (s) + [BaCl6]4− (soln.) → [Ba2OCl6]4− (soln.) and was accompanied by the appearance of [Ba2OCl6]4− groups (D3d symmetry) of a mixed oxychloride composition.
