Abstract

Phase ratios in the subsolidus regions of Rb2MoO4–CaMoO4–R2(MoO4)3 systems (R = Nd, Sm, Eu, or Gd) were studied by vibrational spectroscopy, X-ray diffraction, and differential thermal analysis. Ternary molybdates RbCaR(MoO4)3 (R = Nd, Sm, Eu, Gd) with scheelite derivative structures (monoclinic symmetry system, space group P21/n) were synthesized. Unit cell parameters were determined, and IR and Raman spectra were characterized.
