摘要
分析了制备铁镍钴合金前驱体的Fe-Co-Ni-NH3-C2O42--H2O体系的热力学,计算了溶液体系中Fe(Ⅱ),Ni(Ⅱ),Co(Ⅱ)的浓度与pH的关系,确定了3种金属离子完全共沉淀的最佳pH为2.0。
The thermodynamic analysis on the system of Fe（Ⅱ）-Ni（Ⅱ）-Co（Ⅱ） -NH3-C2O4^2--H2O for preparing Fe-Ni-Co alloy precursor was carried out. The relations between solution pH value and total concentration of Fe（Ⅱ）,Ni（Ⅱ） or Co（Ⅱ） were determined. Suitable pH value of co-precipitation was 2.0.
