By equilibrating the CaO‐Al 2 O 3 ‐SiO 2 slags with Fe ‐ 0.0003∼0.07% Al ‐ 0.002∼3.5% Si ‐ 0.9∼2.0% C alloys (mass contents in %) at 1873 K, the solubilities of carbon were measured as a function of Si contents in metal, using an alumina or lime crucible. The distribution ratios of carbon as a C 2‐ ‐ion were found to be linearly related to Si contents with a slope of 1/2 at a given slag composition. The carbide capacity, , defined by (% C) , increased with increasing SiO 2 contents at a given CaO/AlO 1.5 molar ratio in the CaO‐AlO 1.5 SiO 2 system.
