研究了在700~1000 ℃温度范围内金属锑在Na2CO3?NaCl二元熔盐中的溶解行为.结果表明,金属锑的溶解平衡可以在3 h内完成,同时锑的溶解量随熔体黏度的降低而减少.在700、800、900和1000 ℃时锑的饱和溶解量分别为5.42%、2.42%、0.75% 和0.68%,较高的温度和适量的NaCl含量可以降低锑的溶解量.不溶解的锑沉聚于熔盐底部,不与熔盐反应.溶解在熔盐表面的锑容易被氧化,而溶解于熔盐中的锑以金属态的形式随机地分布于熔盐中,形成夹杂.

The interaction between molten Na2CO3?NaCl salt and Sb and the solubility of Sb in molten salt were investigated in the temperature range of 700?1000 ℃. The results show that the dissolution equilibrium of Sb in molten salt can be achieved in 3 h, and the amount of Sb dissolved in the melt decreases as the viscosity decreases. The solubility limits in an eutectic mixture were determined as 5.42%, 2.42%, 0.75% and 0.68% at 700, 800, 900 and 1000 ℃, respectively. A high temperature and appropriate content of NaCl will decrease the dissolution of Sb. The insoluble Sb was collected at the bottom of molten salt. The Sb dissolved on the surface of the molten salt is easily oxidized, whereas the Sb dissolved inside the molten salt is randomly distributed in terms of the form of metal Sb.
