摘要: Abstract New cadmium and rare-earth metal molybdates with the formula Cd0.25RE0.50MoO4 (RE = Pr, Nd, Sm–Dy) were synthesized by solid-state reaction of CdMoO4 corresponding RE2(MoO4)3. The obtained compounds crystallize in scheelite-type structure. They characterized here XRD, DTA-TG, IR EPR methods. showed solubility forming CdxRE2−2x(MoO4)3−2x (0.50
