Our previous reports described the results of determination of the activity of SiO2 and Al2O3 in the slag of CaO-SiO2-Al2O3 system using the e.m.f method of double cell. As it is difficult to construct the cell with reversible calcium electrode at high temperature, the authors tried to determine the activity of CaO with solid lime at 1630° as the standard using Gibbs-Duhem equation. At first, the activity of CaO on the system CaO-Al2O3 was determined. Then the same calculation was extended to CaO-SiO2-Al2O3 and CaO-SiO2 systems. From these value, the iso-activity lines were drawn on the ternary coordinates of CaO-SiO2-Al2O3. The course of iso-aCaO line was similiar to the so-called sulphur capacity lines. From the activity-composition diagram on the system CaO-SiO2, aCaO saturated with 2CaO.SiO2 was given as 0.25.
