Activity coefficient of AgO 0.5 in PbO-SiO 2 melt equilibrated with Ag-Pb alloy in an alumina or a magnesia crucible was investigated at 1273 K. A chemical equilibrium technique was applied to the measurement. The oxygen partial pressure was also measured by an EMF method. The activity coefficient of AgO 0.5 in the PbO-SiO 2 melt was derived. The addition of SiO 2 in the PbO melt decreases dissolution of Ag into the oxide phases. However, the activity coefficient of AgO 0.5 increases slightly with an increase in the concentration of SiO 2 in the PbO melt.
