A Thermogravimetric technique was used to achieve accurate measurements of carbon dioxide dissolution in molten CaO-CaCl_2-CaF_2 fluxes. The effects of temperature as well as composition of flux on carbon dioxide dissolution are studied. Experiments were conducted at a temperature range from 900 to 1500℃. The solubility in fluxes of X_<CaO_<init.>>=0.12 increased from 0.44 to 0.97wt% as replacing CaCl_2 by CaF_2 at 1100℃ and it decreased from 2.95wt% to 0.21wt% with increasing temperature at constant X_<CaF_2init.> of 0.6. Results obtained in this study were compared with those appearing in the literature. Carbonate capacities calculated from the solubility data at 1500℃ were compared with sulphide capacities, phosphate capacities, phosphide capacities, nitride capacities and cyanide capacities in CaO-CaF_2 system. Linear relations were observed between carbonate capacities and other capacities on log-log plots.
