Phase Diagram of the LiCl-MgCl₂-Na₂cSiO₃-H₂O System at 150°C and Synthesis of Hectorite

Abstract:

The phase equilibrium of the LiCl-MgCl₂-Na₂SiO₃-H₂O (LMNH) quaternary system at 150°C was studied and the phase diagram of the system was plotted, in order to synthesize hectorite with the nature brine, which was rich in lithium and magnesium. The solid phases were characterized by X-ray diffraction (XRD) and Energy Dispersive Spectrometer (EDS). It was found that hectorite, lithium silicate, karpinskite and brucite can be formed in this system.
