| 摘 要： | 研究了Co3O4煅烧过程中阴离子的作用行为。通过对钴沉淀物的热分析、红外光谱分析和化学分析研究表明:钴沉淀物中所含阴离子在煅烧过程中呈现出分解、自氧化效应和空间效应,在尖晶石型Co3O4形成过程中起到提供氧源和空间阻隔的作用,对Co3O4的生成温度、粒度、孔隙率等产生较大的影响。

| Abstract: | The effects of anion during the calcination process for Co3O4 was studied.By means of thermo-analysis,IR analysis and chemical analysis,it was elucidated that the anions,contained in the precipitate,could lead to the formation of decompose,self-oxidation and space effect during thermolysis.The anion could provide oxygen sources and space separation during the process of spinel Co3O4 appearance.It had great effect on temperature,size and porous rate of Co3O4. |
