Abstract
For the establishment of liquid iron-titanium-oxygen equilibria, a thermodynamic study on Ti-O system was achieved. For this purpose, EMF measurements onoxygen concentration cells involving thoria base solid electrolytes were made, in the temperature range from 900 to 1550°C, using Fe/FeO, Cr/Cr203, Ta/Ta205 and “TiO”/“Ti2O3” as reference electrodes. The po2-composition isotherms and the free energy change for titanium oxide formation were deduced from experimental results in Ti-0 system (O/Ti ratio; 0.6, -3/4-2.0, 900, -3/4-4 600°C).Keywords
