Abstract:

Kieserite (MgSO4·H2O) which has great application in recent years, was prepared according to the binary system MgSO4H2O at 80°C and the ternary system MgCl2MgSO4H2O at 25°C, 50°C and 75°C phase diagrams in this research. We reveal that the pure MgSO4·H2O is acquired in the ternary system MgCl2MgSO4H2O at 75°C with MgCl2 (23.966%~37.93%) for the equilibrium time 5~7days. The higher hydrated magnesium sulfate can be obtained in the ternary system with MgCl2 (0~34.52%) at 25°C, (0~35.684%) at 50°C, and (0~23.966%) at 75°C for 5~7days. These results are beneficial for the industrial production by converting MgSO4·7H2O and MgCl2·6H2O which are not fully exploited in salt pans into the useful MgSO4·H2O.
