氧化镁在熔盐中溶解度的研究

Study on Solubility of MgO in Melt Salt

研究了NaF+NaCl、NaCl+冰晶石、NaCl+NaF+冰晶石、Na3PO3+NaF+NaCl、Na3PO3+NaCl+冰晶石5个熔盐体系氧化镁的溶解度。实验结果表明,各熔盐体系中氧化镁最大溶解度依次为1.2%、1.9%、2.1%、1.09%、6.04%。

The solubility of the five melt salts such as NaF＋NaCl, NaCl＋cryolite, NaCl＋NaF＋cryolite, NaaPO3＋NaF＋NaCl and Na3PO3 ＋NaCl＋cryolite are studied. According to the results the five melt salt is sequenced by the extent of solubility as 1.2%, 1.9%, 2.1%, 1.09% 6.04%, which is of significance to electrolyzing magnesia.
