Abstract

A new group of cadmium and rare-earth metal molybdato–tungstates with the formula Cd0.25 RE 0.50□0.25(MoO4)0.25(WO4)0.75 (RE = Pr, Nd, Sm–Dy, □—vacancies in cation sublattice) were synthesized by a high-temperature solid-state reaction between RE 2MoO6 and CdWO4 mixed at the molar ratio of 1:3. Powder X-ray diffraction measurements showed that obtained phases adopt the scheelite-type structure. The phases melt congruently in the temperature range of 1382–1458 K.
