Abstract The activity of CaO in the CaO-B2O3 slag containing volatile component B2O3 has been measured in a partially sealed graphite container in equilibrium between the slag and melt, and the activity of B2O3 has been calculated by integrating Gibbs-Duhem equation. The experimental results are in good agreement with the previous data derived from the phase diagram and free energies of formation.

Key words: CaO-B_2O_3 slag activity volatility
