摘 要: 通过用等温法研究了Sc_2(C_2O_4)_3-Me_2C_2O_4-H_2O(Me=NH_4^+、Na^+、K^+、H^+)体系在30℃时的溶解度相图,摩尔电导测定表明,体系内析离的一系列草酸钪化合物均按络盐形式解离,用热重分析法研究了各种络盐的热分解过程,同时给出了各种络盐的X射线粉末图。 The solubility phase diagrams of the Sc2(C2O4)3 - Me2C2O4 - H2O system have been studied by isothermal method at 30.The results from determination of mole conductance of the com-punds formed by scandium with oxalate ion indicate they were fill dissociated in form of complex salt. These complexes were characterized by thermogravimetric analysis as well as X- ray.
