本文报道了溶解度法研究Yb_2(SO_4)_3-(NH_4)_2SO_4-H_2O三元体系在25℃时的溶解度图。从相图的构成,可确定上述三元体系的相图是固液异组成类型水盐相图。
This paper reports the solubility of Yb_2 (SO_4) _3- (NH_4) _2SO_4-H_2O ternary system at 25 ℃ solubility diagram. From the composition of the phase diagram, it can be confirmed that the phase diagram of the ternary system is a solid-liquid heterofacies-type water-salt phase diagram.
