| 摘 要： | 前言水盐三组分体系相图的制作方法颇多,常用的有干渣法、湿渣法、冷却法及合成复体法等。这些方法虽各有其特点,但一般说来都较繁复费时,常常既要测定平衡体系中饱和溶液的组成,且要测定平衡体系的固相组成。 E.L.Heric曾提出一种只需测定平衡体系中饱和溶液的水含量,便可制作出水盐三组分体系相图的方法,颇具特色。其原理是:若以a、b、c分别表示试样中水、盐Ⅰ和盐Ⅱ的重量百分数;以a_s,b_s,c_s分别表示已达溶解平衡的饱和溶液中的水,盐Ⅰ和盐Ⅱ的重量百分

| Abstract: | E. L. Heric presented an improved method of compound synthesis that indicated the ternary aqua-sahs phase diagram can be constructed by determining only the aqueous content of the saturated solution in the equilibrium system. Based on Heric's principle an experimental study in constructing aqua-salts phase digrams for four basic types of NaNO_3-Pb(NO_3)_2-H_2O, NH_4Cl-BaCl_2-Ha_2WO_4-Na_2MoO_4-H_2O, Na_2SO_4-MgSO_4-H_2O system was completed, and the results showed fairly consistent with the data in literatures. It proves that Heric's method is feasible. In this paper, the experimental study is described in detail, and the reliability and applicability of Heric's method are discussed. |
