AbstractThe influence of NaCl-CaCl2 on thermal decomposition of REPO,(RE: Ce, La, Nd, Th) with CaO was studied. The heat decomposing process of REPO, was tested with TG-DTA experiments. The results showed that the decomposition temperature of REPO, with CaO was reduced because of adding NaCl-CaCl2 mixture (NaCl:CaCl2 = 1:1). The influence of the addition of NaCl-CaCl2, roasting temperature and roasting time on decomposition ratio of REPO, with CaO was studied. The results showed that the decomposition ratio of REPO,with CaO was 79% when the addition percentage of NaCl-CaCl2 was 10%, the roasting temperature was 750 degrees C, and the roasting time was 1 h.
