摘要	The crystallization processes of hydrated Mg-borates, boric, magnesium hydroxide and Mg-oxychloride from MgO-B2O3-18%MgCl2-H2O supersaturated solution at 20degreesC have been studied by kinetic method. The crystallization solid phases were characterized by X-ray powder diffraction, IR spectra, thermal analysis and chemical analysis. The liquid-solid phase diagram of thermodynamic nonequilibrium state has been given. In this phase diagram, there exist eight crystallization fields, boric acid(H3BO3), trigomagneborite(MgO . 3B(2)O(3) . 7.5H(2)O, MgO . 3B(2)O(3) . 7H(2)O), hungchaoite(MgO . 2B(2)O(3) . 9H(2)O), inderite(2MgO . 3B(2)O(3) . 15H(2)O), chloropinnoite(2MgO . 2B(2)O(3) . MgCl2 . 14H(2)O), magnesium hydroxide(Mg(OH)(2)) and magnesium oxychloride (5Mg(OH)(2) . MgCl2 8H(2)O).
