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 文摘:利用肼(或肼盐)易分解同时释放大量的热和气体这一特点，将肼(或肼盐)添加到草酸稀土中去，热分解含肼稀土草酸盐可制得比表面积较常法制备的大得多的稀土氧化物。
