摘要: The waste LiCl-Li2O oxide reduction salt was solidified and transformed into sodalite by the spark plasma sintering method. Compared with traditional solidification method, SPS operates at a lower pressure, lower temperature, shorter processing time, and without sintering additive. The SPS-solidified sodalite presents a low porosity of 0.37% and low leaching rates of 2.21 g m(-2) d(-1) for Cs, 3.05 x 10(-1) g m(-2) d(-1) for Ba, and 3.12 x 10(-1) g m(-2) d(-1) for Sr. Overall, the SPS is a promising method to solidify various waste OR salts.
