Phase equilibria in the Li 2 MoO 4 -Ln 2 (MoO 4 ) 3 -Hf(MoO 4 ) 2 (Ln = La-Lu) systems

Subsolidus phase relations in the Li2MoO4-Ln2(MoO4)3-Hf(MoO4)2 (Ln = La-Lu) systems have been studied by the method of “intersecting cuts,” and the phase compatibility diagrams of the systems have been constructed using X-ray diffraction data. The systems can be divided into five groups according to the nature of their phase compatibility diagrams. No new triple molybdates have been identified in the systems studied.
