【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%Mgck2, 1.77% MgSO4 and 0.65% H3BO3.更多还原
