ABSTRACT:

 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.
