Phase Equilibrium Study at 220°C of Li+,Mg2+//Cl-, SiO32--H2O Systerm
In this paper, phase equilibrium of Li+, Mg2+∥Cl-, SiO32--H2O system at 220°C was researched. The solid phases were characterized by X-ray diffraction (XRD). Lithium silicate, hectorite, karpinskite and magnesium hydroxide were observed as solid phases. According to the analysis of XRD, the phase diagram was obtained. The phase diagram could be used as the theoretical principle for synthesis of hectorite.
