Abstract
The effect of the solvent metal on the composition of titanium oxides formed at the interface of a Ti-containing melt with Al2O3 was analyzed. The fact that titanium in dilute solution is oxidized to a higher degree than in the pure form is thermodynamically connected with the bond energy between the solvent metal and aluminum transferred from the alumina to the melt. Recommendations for controlling the oxygen concentration of the reaction products are given.
