用CdWO 4与相应的RE_2 W_2 O_9固相反应合成了新的镉和稀土金属钨酸盐，分子式为Cd_（0.25）RE_（0.50）square_（0.25）WO_4（RE=Nd，Sm，Eu，Gd，阳离子亚晶格中空位呈正方形分布）。所获得的相以白钨矿型结构结晶。用X射线衍射（XRD）、差热-热重（DTA-TG）、红外光谱（IR）和电子顺磁共振（EPR）等方法对Cd_（0.25）RE_（0.50）方_（0.25）WO_4化合物进行了表征。
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.
