摘 要: 研究了鎢摻雜對草酸鈷結構和微觀形貌的影響。用X射線衍射及掃描電鏡分析了摻鎢草酸鈷的晶型結構及形貌，還用BET儀測量了粉體的比表面。結果表明，鎢摻雜使草酸鈷由α-晶型轉變?yōu)?I>β-晶型，摻雜草酸鈷的形貌也發(fā)生了相應變化。隨著摻鎢量的增加，其一次顆粒的平均粒度顯著變小。

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
