| 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. |
