| Abstract: |
| Activity of aluminum ash and sandy alumina are analyzed used the electron microscope scanning in this paper. It is concluded that α-Al2O3 in the aluminum ash is very stable and its activity is very poor, which is difficult to ionize in the aluminum electrolysis process. So it is not favorable to return aluminum reduction cell and recycle.S |
