The activity of tin in Ti-Sn alloy has been determined at 1400 K by Knudsen effusion method with electrobalance. The activity of titanium was calculated by applying the Gibbs-Duhem relation to the Ti-Sn binary system. The standard Gibbs energy of the formation of intermetallic compound such as Ti 3Sn, Ti2Sn, Ti6Sn3 and Ti 6Sn5 was calculated at 1400 K by using the activities of components. X-ray diffraction studies were additionally conducted for some samples after the activity measurement. The identified phases were consistent with the phase diagram reported in the literature.
