摘要
Vacuum evaporation of a LiCl-BaCl2-SrCl2 system was investigated to design a process for waste reduction and salt recycling. Through thermo-gravimetric analysis (TGA) tests of pure LiCl at a reduced pressure, a model equation for LiCl vaporization was established. As results of TGA tests of pure BaCl2 and SrCl2, it was confirmed that they were very stable at 900 掳C and 0.5 Torr. At 1 Torr, evaporation of the LiCl-BaCl2-SrCl2 system looked similar to the pure LiCl vaporization results. Co-evaporation of BaCl2 or SrCl2 with LiCl was very slight in this study.
