- There are many combinations of metal oxide and aluminum that
- are possible.
-
- The resultant products are basically Al2O3 and a reduced metal.
- Impurities remaining depend on the mixture proportions, as well
- as the efficiency of the reaction.
-
- Note that magnesium will do the same thing. It is just more
- expensive, as well as being more hazardous to work with.
