对制备钐铁合金前驱体的Sm(Ⅲ)-Fe(Ⅱ)-NH3.H2O-NH4HCO3-H2O体系进行了热力学分析,给出了溶液中Sm(Ⅲ)、Fe(Ⅱ)浓度与pH值的关系,确定了两种金属离子完全共沉淀的最佳pH为7.0。
Abstract：Thermodynamic analysis on the system of Sm(Ⅲ)-Fe(Ⅱ)NH3·H2O-NH4HCO3-H2O to prepare Sm-Fe alloy precursor was carried out.The relations between the system pH value and total concentration of Sm(Ⅲ) and Fe(Ⅱ) were determined.Suitable pH value of co-precipitation was 7.0.
