Activity of SiO2 in ((1-X)B2O3+xsio(2)) Determined by (Slag Plus Metal) Equilibrium at the Temperature 1723 K, Using (0.25 Cu+0.75 Sn) as Metal Solvent
(Slag + metal) equilibrium experiments have been made for the determination of activity of SiO2 in the {(1-x)B2O3 + xSiO(2)} slag at the temperature T = 1723 K, using (0.25 Cu + 0.75 Sn) as a metal solvent. The results indicate a positive deviation from ideality. The activity of B2O3 was calculated from the Gibbs-Duhem equation.
