摘　　要：研究了添加活性球化剂对草酸钴形貌的影响 ,利用X衍射仪对工业草酸钴和球形草酸钴的结构进行分析 ,同时用扫描电镜观察它们的形貌 ,实验表明 ,添加活性球化剂在不改变草酸钴晶体结构的前提下 ,使其外观形貌发生了明显的变化 ,从而改善了其物理性能。Study is made of the influence of active spheroidization agent on the morphology of the cobalt oxalate.Analysis is made of the microstructures of industrial cobalt oxalate and spheroidial cobalt oxalate by X-diffractmeter and their morphology is observed under scanning eletron microscope.The experiment results showed addition of active spheroidization agent can result in distinct morphology change with better physical properties on the prerequisite of unchanged crystalline structure of the cobalt oxalate.
