DETERMINATION OF THE ACTIVITIES OF MgCl2 IN THE MOLTEN MgCl2-KCl-CaCl2 SYSTEM BY EMF MEASUREMENTS
【摘要】 本文采用生成原电池Mg(Bi)(液)|MgCl2-KCl-CaCl2(液)|Cl2(气)石墨,在温度范围690至850℃内,对浓度不同的MgCl2-KCl-CaCl2三元熔盐电解质进行了实验研究,根据电动势的测定结果,计算了MgCl2在该三元熔体中的活度及若干其它热力学性质。
【Abstract】 Based on the electromotive force measurements and using the reversible formation cell Mg-Bi(L) |MgCl2-KCl-CaCl2 (L)| Cl2 (G) (Graphite), the activities and some thermodynamic properties of MgCl2 in the molten MgCl2-KCl-CaCl2 system have been determined. The investigation tem- perature range was from 690 to 850℃. The composition changed from mole fraction of MgCl2 0.100 to 0. 850 with the ratios of CaCl2 to KCl 0. 5 and 2 respectively.
