The activity of zinc oxide in multicomponent slags has been investigated. Activities were determined experimentally Toy equilibrating iron saturated brasses with slags containing iron oxide. Required activities in the Zn-Cu-Fe system were obtained from experimental iron saturation data and available information on the Zn-Cu and Cu-Fe systems. Where measurement was not possible, thermodynamic analyses of slag systems were carried out. Rigid activity patterns in the ZnO-SiO₂, ZnO-FeO-SiO₂, ZnO-CaO-SiO₂ and ZnO-FeO-CaO-SiO₂ systems have been developed from experimental and analytical data. Agreement with the activity data of Bell, Turner and Peters on ZnO-FeO-CaO-SiO₂ and Okunev and Bovykin on ZnO-FeO-SiO₂ type slags indicates that the present measurement technique provides a good basis for industrial slag investigations. === Applied Science, Faculty of === Mining Engineering, Keevil Institute of === Graduate
