以硝酸铈、硝酸钕、硝酸钇、磷酸和氨水为主要原料采用共沉淀的方法合成掺杂钕（钇）的独居石固化体。通过X射线衍射仪,扫描电子显微镜,电子探针等分析技术研究钕-独居石固化体和钇-独居石固化体的化学组成和微观结构。结果表明,钕元素可以做为替代元素模拟核废物中的三价放射性核素掺杂到独居石固化体中,而钇元素则不可以。

The Nd(Y)-monazite was synthesized by using Ce(NO3)·6H2O,Nd(NO3)·6H2O,Y(NO3)·6H2O,H3PO4 and NH4OH as the raw materials with co-precipitation method.The chemical composition and microstructure of Nd-monazite and Y-monazite were tested by the X-ray diffraction,scanning election microscopy and electron probe microanalysis.As a result,neodymium element can be as the instead element that simulate the nuclear waste with trivalence radioactive elements to the monazite solidified body but the Yttrium can't.
