Abstract This paper describes the bubbling of AlCl 3 gas in molten aluminum for the purpose of obtaining a more reliable value of the equilibrium constant of subhalide reaction and for clarifying the effects of alloying elements on this reaction. By reducing the hole diameter of bubbling tube from 5 to 1mmφ, the reaction arrived in equilibrium state and the equilibrium constant was directly determined in the temperature range of 1, 0001, 200°C. The relation between the equilibrium constant and the standard free energy was expressed by the following equations: log K p=-16.7×10 3/ T+11.4 Δ G° T=76, 200-52.2 T The reactivity of AlCl 3 with Al-Si or Al-Fe binary alloys was also investigated by the bubbling method. In consideration of the results of these experiments and the equilibrium constant, the activities of aluminum in these alloys were determined at 1, 200°C. The activity curves determined in these experiments were in good agreement with those previously obtained by other authors.

The contents of Fe and Si in Al derived from Al-Fe or Al-Si binary alloys were determined by emission spectroanalysis. The results showed that the Fe content was little, but the Si content was always constant at 0.25% independent of the presence of Si in the original material. The introduction of Si and Fe to the product was discussed by thermodynamic calculations on the experimental data. It was made clear that the introduction resulted from the reaction between the oxide of Si or Fe and AlCl or AlCl 3.
