摘要： 作者考察了H3BO3-MgSO4-MgCl2-H2O四元体系在273.15±0.05K温度下的溶解度等温线。四元体系共饱和点的液相组成为33.44%(重量)MgCl3,1.77%MgSO4和0.65%H3B03。

Abstract: The quaternary system of H3BO3-MgSO4-MgCl2-H2O has been investigated at 273.15+0.05K by means of the isothermal method. This system is composed of three simple ternary systems:H3BO3-MgCl2-H2O (Ⅰ), H3BO3-MgSO4-H2O (Ⅱ) and MgCl3-MgSO4-H2O (Ⅲ). The solid phases identified are. (Ⅰ) H3BO3+MgCl2·6H3O;(Ⅱ) H3BO3+MgSO4·7H3O and (Ⅲ) MgCl2·6H2O+MgSO4·7H3O.There are three regions of the solid phases:H3BO3, MgCl2·6H2O and MgSO4· 7H2O in the central projection diagram. The eutectic point is at 33.44 Wt% MgCl2, 1.77% MgSO4and 0.65% H3BO3.
