chloride melts, solubility, oxychloride complexes
The solubility of B2O3 in molten CaCl2 without additives and with additives of CaO was determined using visual observation, spectroscopy, Raman scattering (RAMAN), and X-ray phase analysis. The boron oxide was proved to be not soluble in the pure molten calcium chloride. The interaction is possible only in the presence of a certain amount of calcium oxide in the melt with the formation of various calcium borates.
