| Abstract: | A method for preparation of rare earth oxides with high specific surface area was described.Hydrazine containing rare earth oxalates as the precursors were synthesized by using rare earth oxalates and hydrazine.The specific surface area of rare earth oxides made by the method described in this paper is higher than that by the usual method. |
