摘要
本文以RE_2O_3和(NH_4)_2HPO_4为原料制备了REPO_4(RE:La—Lu,Sc和Y)系列样品。研究了REPO_4化合物中磁化率与RE^(3+)离子原子序数的关系。REPO_4的结构分为单斜晶系(La—Gd,Tb)和锆英石型(Tb—Lu,Sc和Y)二种类型结构,测定和讨论了化合物的光谱。
A series of REPO_4 (RE_2 La—Lu, Sc and Y) were prepared from RE_2O_3 and (NH_4)_2HPO_4. Dependence of the magnetic susceptibilities on the atomic number of RE^(2+) ions in the REPO_4 were studied. The structure of REPO_4 can be classified into two types_2 monazite (La—Gd, Tb) and zircon(Tb—Lu, Sc and Y) structure. The spectra of the compounds are measured and discussed.
