Conversion reactions of metal chlorides into oxides with boric acid (H3BO3) were studied to develop the method for vitrification of radioactive molten salt wastes generated in the pyroreprocessing process. Mixtures of metal chlorides and H3BO3 with appropriate compositions in Pt crucible were heated at 1, 000°C for 1h in an electric furnace, followed by rapid cooling to room temperature. The chloride compounds used were LiCl, NaCl, KCl, CsCl, SrCl2, BaCl2•2H2O, and CeCl3•6H2O. All chlorides other than CsCl were found to be transformed into oxides (borate glass) in the molar ratios of H3BO3/chlorides ?? 2. Furthermore, four-component systems, i.e., the mixtures of LiCl, KCl, NaCl (or SrCl2, BaCl2•2H2O, CeCl3•6H2O), and H3BO3 were also examined in a similar manner. The borate glasses were found to be formed in the molar ratio of H3BO3/chlorides ?? 2.
