The activities of MoO 2 in the (Ti,Mo)O 2 solid solution were measured at seven different compositions, using an emf method involving calcia‐stabilized zircoinih as solid electrolyte. In the temperature range studied, 1350 to 1600 K, the activities of MoO 2 show a strong positive deviation from ideal behavior. In addition, the solvus of the TiO 2 ‐MoO 2 system was determined with the equilibration and quenching technique. The solvus maximum was found at T = 1420 ± 5 K and X(MoO 2 ) = 0.85 ± 0.05.
