Activity Measurements of the Ternary Liquid Al–Si–Fe System by the EMF Method

Abstract

In this report, the activities of Al in the ternary liquid AI-Si-Fe system were determined by emf measurements of the reversible concentration cell Using the obtained activities of Al, the activities of Si and Fe at 1000•‹C were calculated by Schuhmann's tangent intercept procedure. Judging from the obtained activities of Al, Si and Fe, the liquid AI-Si-Fe alloy with is most suitable to the subhalide process as the raw material.
