Abstract
E.M.F. of galvanic cell (-)W\Zn,ZnO\ZrO2(+Y2O3)\Zn-Bi,ZnO\W(+) was mea sured to determine the activity of zinc in the whole composition range at 750-950K for liquid Zn-Bi alloys. The activity of zinc in the allo ys shows large positive deviations from Raoult's law. From the activit y data the concentration fluctuations at long wave length limit Scc(0) are calculated and compared with the model calculation for demixing l iquid binary alloy. The miscibility gap are derived from E vs T plot.
