Aqueous speciation of cadmium in 2 M chloride solutions was determined at 500 and 600°C, 1 kbar and 600°C, 0.5 kbar in the system CaTiO3-CdTiO3-CaCl2-CdCl2-NaCl-H2O using the same experimental method as Uchida et al. (1998). Thermodynamic analysis of the experimental results gives 1.3, 2.3 and 2.9 for the logarithm of the stepwise formation constant of tri-chloro cadmium complex at 500 and 600°C, 1 kbar and 600°C, 0.5 kbar, respectively. The formation constant increases with increasing temperature and decreasing pressure.
