| 英文摘要 | Consecutive microwave sintering is a method proposed in this study to dispose soil contaminated by Sr during a nuclear accident by rapidly solidifying the contaminated soil. The results show that soil contaminated with 20 wt % SrSO4 and 30 wt% SrSO4 can be completely solidified by microwave sintering at 1100-1200 and 1300 degrees C, respectively, for 30 min. Sr was found to be cured into slawsonite (SrAl2Si2O8) and glass structures. Moreover, soil sintered at 1300 degrees C has large cured solubility (30 wt.%), good uniformity, and excellent hardness (6.9-7.2 GPa) and chemical durability (below 1.46 x 10(-5) g m(2) d(-1) at 28 d). Thus, consecutive microwave sintering technology may provide a new method for treating Sr-contaminated soil in case of a nuclear accident emergency. |
