Abstract

The phase equilibrium diagram of the system ThO₂‐Nb₂O was redetermined near the composition Th₂Nb₂O₉. This phase was found to melt incongruenlly at 1362°C, with a eutectic temperature at ∼1350°C. The peritectic and eutectic compositions must occur between 60 and ∼64 mol % ThO₂. From single crystal and powder X‐ray diffraction data, Th₂ Nb₂O₉ was found to have a primitive monoclinic unit cell with a = 6.711(1), b = 25.254(5), c=7.757(1)×10⁻¹nm, β=90.46 (1)°.
