The first-order (ega) and the second-order (rga rg o ) interaction parameters betweencalcium and oxygen in liquid iron were determined at 1 873 K by using the previous data obtained in slag-metal equilibrium experiments, on the basis of the reciprocal and conversion relationships between mass percent and mole fraction scales. Thevalues for ega, rg and rg, o were obtained as -3 600, 5.7 x I 05 and 2.9 x I 06 jn the range of {[masso/oCa] +2.51 [masso/oO]} and -990, 4.2x I 04 and 2.1 x I 05 jn the range of {[masso/oCa] + 2.51 [massoloO] } ~: O.005, respectively, and the validity of these values was discussed.
