采用简单的溶剂热法制备了不同尺寸和形貌的钴微晶。分别考察了不同溶剂对产物尺寸和形貌的影响。在乙醇中可以得到直径在几十微米左右的花状钴。同时，分别在乙二醇和甘油中制备了边缘长度在几微米左右的微盘和八面体。溶剂的还原电位和粘度等级对控制钴的大小和形貌起着重要的作用。此外，室温磁性测量表明，钴微晶的磁性与其形貌有关。
Cobalt microcrystals with different sizes and morphologies were fabricated via a facile solvothermal method. The effects of different solvents on the sizes and morphologies are investigated separately. Flowerlike cobalt with around tens of microns in diameter is obtained in ethanol. Meanwhile, of microdisks and octadecahedra with the edge lengths about several microns are fabricated in ethylene glycol and glycerol, respectively. Reduction potential and viscosity rank of the solvents play the important roles in controlling the sizes and morphologies of cobalt. Moreover, room-temperature magnetic measurement shows that the magnetic properties of cobalt microcrystals depend on their morphologies.
