The solid liquid phase equilibria and species chemical equilibrium of Mg(BO₂)₂ dissociated in MgCl₂ aqueous solution were studied by means of Raman spectroscopy and X ray diffraction (XRD). The results indicate that the MgCl₂ concentration has a great influence Mg(BO₂)₂ dissociation. (1) With the increasing of MgCl₂ concentration from 0 to saturated state, the apparent solubility of Mg(BO₂)₂ increased from 0.79% to 1.96%, and pH value decreased from 9.96 to 6.27; (2) Solid species are changed gradually from Mg₂B₆O₁₁·15H₂O and Mg(OH)₂, to Mg₂B₆O₁₁·15H₂O and Mg₃Cl₂(OH)₄·4H₂O; (3) Main species of polylobate anions change from B₄O₅(OH)₄^2- and B₃O₃(OH)₄^- with the accounts of 49.81% and 19.54%, to B₃O₃(OH)₄^- and B₅O₆OH)₄^- with accounts of 44.57% and 40.00%, respectively.
