New cadmium and rare earth metal tungstates with the scheelite type structure

New cadmium and rare earth metal tungstates with the formula Cd0.25RE0.50 square 0.25WO4 (RE=Nd, Sm, Eu, Gd, square-statisfical distributed vacancies in cation sublattice) were synthesized by the solid-state reaction between CdWO4 and corresponding RE2W2O9. The obtained phases crystallize in the scheelite type structure. The Cd0.25RE0.50 square 0.25WO4 compounds were characterized by X-ray diffractometer (XRD), (DTA-TG), infrared (IR) and EPR methods.
