Subsolidus phase diagrams for the Tl2MoO4-Ln2(MoO4)3-Hf(MoO4)2 systems, where Ln = La-Lu

The Tl2MoO4-Ln2(MoO4)3-Hf(MoO4)2 systems where Ln = La-Lu were studied in the subsolidus region using X-ray powder diffraction and IR-Spectrometry. New ternary molybdates were prepared: Tl5LnHf(MoO4)6 (5:1:2) for Ln = Ce-Lu, TlLnHf0.5(MoO4)3 (1:1:1) for Ln = Ce-Nd, and Tl2LnHf2(MoO4)6.5 (2:1:4) for Ln = Ce-Lu. The crystallographic parameters of Tl5LnHf(MoO4)6 (5:1:2) compounds for Ln = Er-Lu were determined.
