研究了２５℃ＮＨ４Ｃｌ－ＫＣｌ－Ｈ２Ｏ三元体系的固液相平衡关系，测定出有关溶解度数据， 结果表明该体系存在纯 ＮＨ４Ｃｌ、纯 ＫＣｌ、 ＮＨ４Ｃｌ为主的固溶体及 ＫＣｌ为主的固溶体等 ４个 结晶区．
The solid-liquid equilibrium relationship of NH4Cl-KCl-H2O ternary system at 25 ℃ was studied. The solubility data were determined. The results showed that there are 4 solid solutions with pure NH4Cl, pure KCl and NH4Cl as main solid solution and KCl as the solid solution Crystalline area.
