Surface Tension in a Cu-Pb-Fe Liquid Alloy (X_Cu=0.9)/Al₂O₃/Gaseous Phase System

Abstract:

The surface tension of the liquid ternary Cu-Pb-Fe alloys at the constant content of copper (X_Cu=0.9)-refractory material Al₂O₃-gaseous phase was determined. The experiments were performed in the range of temperature between 1100 and 1350 °C at the different content of lead and iron (X_Fe/X_Pb+X_Fe). The surface tension was determined by sessile drop method. The composition of the investigated alloys corresponds to the composition of the Cu-Pb-Fe alloys obtained via the reduction of the slag obtained during the direct-to-blister flash smelting process in an electric furnace. Images of the liquid drops were made using the X-ray technique and the surface tension values were calculated using the corresponding software programs.
