摘 要: 研究了钨掺杂对草酸钴结构和微观形貌的影响。用X射线衍射及扫描电镜分析了掺钨草酸钴的晶型结构及形貌，还用BET仪测量了粉体的比表面。结果表明，钨掺杂使草酸钴由α-晶型转变为β-晶型，掺杂草酸钴的形貌也发生了相应变化。随着掺钨量的增加，其一次颗粒的平均粒度显著变小。

Abstract:The influences of tungsten-doping upon the structure and morphology of cobalt oxalate were studied. Crystal type was measured by X-ray diffraction, morphology by SEM, and the specific surface area by BET meter. The experiments showed that tungsten-doping results in a transformation of cobalt oxalate from α-type into β-type, and that the morphology of tungsten-doped cobalt oxalate changes greatly as compared to pure cobalt oxalate. With the increase of doped tungsten, the average particle size of its primary grain gets smaller.
Key words: tungsten-doping cobalt oxalate structure morphology
