Scheelite-Related Triple Molybdates KCaLn(MoO4)3 in K2MoO4–CaMoO4–Ln2(MoO4)3 (Ln = Nd, Sm, Eu, Gd) Systems: Synthesis and Characterization

Аннотация

Subsolidus phase ratios in K₂MoO_4–CaMoO₄–Ln₂(MoO₄)₃ systems where Ln = Nd, Sm, Eu, and Gd, have been studied by vibrational spectroscopy, X-ray powder diffraction, and differential thermal analysis. Triple molybdates KCaLn(MoO₄)₃ (Ln = Nd, Sm, Eu, and Gd) have been synthesized; they have a scheelite-derivative structure, monoclinic crystal system (space group P21/n). Their unit cell parameters have been determined, and IR and Raman spectra characterized.
