| 摘要 | The metastable phase equilibria of the Li+, Mg2+//SO42-, borate-H2O system at 273.15 K were studied using isothermal evaporation method. The dry-salt phase diagram, water-phase diagram and the physicochemical property diagrams of the system were plotted with the metastable solubility values and physicochemical properties corresponding to density, refractive index, pH value and conductivity. The dry-salt diagram was composed of four crystallizing zones [lithium sulfate hydrate(Li2SO4 center dot H2O), epsomite(MgSO4 center dot 7H(2)O), lithium metaborate octahydrate(LiB02.8H20), and hungchaoite(MgB407 center dot 9H20)], five univariant curves and two invariant points (Li2SO4 center dot H2O+MgSO(4 center dot)7H(2)O+MgB4O7 center dot 9H(2)O and Li2SO4 center dot H2O+LiBO2 center dot 8H(2)O+Mg4O7 center dot 9H(2)O)center dot Li2B4O7 converted into LiBO2 in solution. Comparing the metastable phase diagram at 273.15 K and stable phase diagram at 298.15 K for the system, the crystallized area of Li2SO4 center dot H2O and MgSOO4 center dot 7H(2)O became large, whereas, the other phase regions became small. The J(H2O) changes regularly with increasing J(SO42-), and the physicochemical properties change regularly with the concentration of B4O72- increasing. |
