The Effect of Lead on the Activity of Sodium in Liquid Zinc X.Y. YAN, D.E. LANGBERG, and W.J. RANKIN The zinc produced by smelting contains many impurities, mainly lead, cadmium, iron, copper, tin, bismuth, cobalt, arsenic, and antimony. The zinc produced from the Imperial Smelting Furnace (ISF) process contains on average 1.0 to 1.3 pct lead and 0.03 to 0.05 pct arsenic. The arsenic content can be readily reduced to below 0.003 pct arsenic by treatment with sodium. A knowledge of the thermodynamic activity data of sodium in zinc and how it is affected by the major contaminant lead is required to determine the end point of the sodium additions. Thermodynamic properties of liquid binary Zn-Na alloys have been studied by several investigators,[1–5] but the effect of lead on the activity of sodium in molten zinc has not been determined experimentally.
