摘要
The activity of titanium in Fe-Cr melts was measured using a galvanic cell technique. By measuring the activity of oxygen in equilibrium with the molten metal and solid titanium oxide, in conjunction with the analysis of the samples for titanium, the activity coefficient of Ti was measured at 1873 K. Oxygen cells, comprised of a thoria-yttria electrolyte with a Cr-Cr2O3 reference electrode and an Al2O3 (ZrO2)-MO cermet tipped molybdenum lead wire, were used to take the electromotive force (EMF) measurements. The measured values of gamma(o)(Ti) and e(Ti)(Cr) were 0.018 and 0.1032, respectively.
