Equilibrium CO2 partial pressures in the systems BaO-BaCO3 and BaO-BaCO3-BaF2 were measured by using the thermo-balance. The results are summarized as follows, <BR>(1) Dissociation of BaCO3 under PCO<SUB>2</SUB> = 1 atm occurs at 1645 K and the temperature decreases with decreasing the partial pressure of CO2.<BR>(2) Interaction parameter on the assumption of regular solution for BaO-BaCO3 melts changed from -23 kJ/mol at 1598 K to -15 kJ/mol at 1773 K.<BR>(3) Gibbs energy of the reaction BaO (melt) + CO2(g) = BaCO3(melt)ΔG°is given by the following relation, <BR>ΔG°=-0.152T + 279(kJ/mol)<BR>(4) Assuming that BaO-BaCO3-BaF2 melts behave as the regular solution, the calculated values of solubility of CO2 in BaO-BaF2 melts are fairly in good agreement with measured ones except for those under PCO<SUB>2</SUB> = 1 atm.
