Description
The technological parameters of simulation solution of Am-Cm transforming into oxides were gained by reduced pressure distillation heated with microwave or oil bath. The simulation solution is made up of Nd, whose properties are similar as Am and Cm, high-concentration HNO3 and rare earth. Calcination of solid was gained by the high temperature concentrated solution in order to get the oxides. The properties of the oxides were investigated by ICP-AES, X-ray diffraction and surface analysis. The results show that the oxide properties gained by reduced pressure distillation and microwave heating method are better than that of oil bath. The concentrating time is decreased, the contents of rare earth elements are very small, and lots of HNO3 can be recycled. (authors)
