| 摘 要： | 本文讨论了６００～１２００Ｋ范围内使用ＮａＣｌ作为添加剂焙烧钒渣时氯化发镓的热力可靠性。结论是：氯氧比的大小与溶性钒酸钠生成有直接联系，ＮａＣｌ和Ｎａ２Ｏ。Ｖ２Ｏ５平衡时的氯氧比最大；在氯化钠作用下，镓主要生成ＧａＣｌ３挥发，计算得到的ＧａＣｌ３的生成压相当大。

| Abstract: | This paper deals with,from the point of view of thermodynamics,the possibility of NaCl addition to chloridizing Volatilization of Ga during Sodiumination roasting of V-slag,in a temperature range 600~1200K. Conclusions are drawn that the magnitude of Cl2-O2 ratio is considerably related to the formation of aqueous sodium vana-date and reaches its maximum value, when NaCl and Na2O ?V2O5 are at equilibrium state; and GaCl3 comes from Ga by chloridization and then volatilizes. Also.the thermo-dynamic calculation shows that the formation pressure of GaCl3 is quite high, therefore the attempt is worthy to be made. |
