Silicon-oxygen equilibria in an Fe-0.003 ~ 27 mass pct Si alloy in equilibrium with the CaO-SiO2 slags were studied in the temperature range of 1823 to 1923 K using a lime crucible. At the same time, nitrogen distribution ratios, LN, between slag and metal were measured, and from these results and the reported values for activities of SiO2, nitride capacities, {Mathematical expression}, defined by (mass pct N). {Mathematical expression} were evaluated. It was found that the values for LN decreased, whereas those for {Mathematical expression} increased with an increase in temperature. Activities of SiO2 were determined using the values for LN and {Mathematical expression} obtained in previous gas-slag experiments. These values were compared with the previous results.
