摘要 采用等温溶解平衡法,研究了三元体系NaCl-CaCl2-H2O 25℃时的溶解度,确定了该体系共饱点的组成,共饱点液相组成是NaCl 0.75%,CaCl244.99%、H2O 54.26%。对应的平衡固相为CaCl2.6H2O和NaCl。两种原始组分未形成复盐或固溶体,体系属于简单共饱型。 The solubility in the ternary system NaC1-CaC12-H2O at 25 ℃ was studied by isothermal method, and invariant point was obtained. Its composition was NaC1, CaC12 and H2O of which content was 0. 75% ,d4. 90% and 54. 26%. The system consisted of two branches corresponding to crystallization zone of CaCl2 · 6H20 and NaC1. No double salt and solid solution, and neither of the two original salts dehydration were found in the system. The ternary system NaC1-CaC12-H2O at 25 ℃ was a simple type.
