铈掺杂对钴草酸盐结构和形貌的影响

EFFECT OF Ce-DOPING ON STRUCTURE AND MORPHOLOGY OF COBALT OXALATE

用化学方法使体均匀掺入草酸钴中。测量了试样的FSSS粒度。用X－ray衍射仪、SEM等分析了样品的结构和形貌。结果表明：铈掺杂使草酸钴的粒度增加；流动性变好；较大的Ce掺杂量使钴草酸盐的结构由α－晶型转变为β－晶型。

Ce was doped into cobalt evenly using chemical method. Fisher size of specimens was measured. Structure and morphology were analyzed by X-ray diffraction and SEM. The experimental results show that tbe grain sise of Ce-doped cohalt oxalate increases and its movability gets better as compared to pure cobalt oxalate. Quite amount of Ce-doping results in variation of structure of cobalt oxalate from a-type to β-type.
