However, I have no practical experience whatsoever so it may very well be lower. If you are carrying out the reaction, experiment with the temperature and see what results you get. I'd love to hear them myself :) | |

If there are issues with diffusion it would also suggest to me that this would work best if the components were mixed before they were expected to react. Floating the iron oxide on aluminium might be expected to work at the interface though. I suppose there is hope but it is going to have very hot molten aluminium to get it going. | |
