摘要：

The equilibria between metallic gallium and its chlorides was studied at 390-520°C by measuring the emf of the galvanic cells. An expression is found for the equilibrium constant of the reduction reaction of gallium trichloride into its monochloride by metallic gallium in the melt: K + -1.815 - 1996/T. The concentration of the trichloride decreases in the mixture with increasing temperature and decreasing total concentration and correspondingly, the average valence of the gallium ions decreases from 2.46 at 673 K an 2.48 mole % to 1.54 at 773 K and 0.53 mole %. From the experimental data, the change in Gibbs energy is calculated for the formation reaction of dilute gallium chloride solutions in the molten chloride.
