Abstract: New cadmium and rare earth metal tungstates with the formula Cd0.25RE0.50□0.25WO4 (RE=Nd,Sm,Eu,Gd,□-statistical 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□0.25WO4 cornpounds were characterized by X-ray diffractometer (XRD),(DTA-TG),infrared (IR) and EPR methods.
