made from aluminum powder and a metal oxide [usually iron oxide (Fe2O3‚ known as rust)]. The thermite reaction is a redox reaction‚ where Aluminum reduces the oxide of another metal. For example‚ when using iron oxide (as I did) the equation would be Fe2O3(s) + 2 Al(s) -> Al2O3(s) + 2 Fe(l). Black or blue iron oxide (Fe3O4) could also be used. Other examples of possible oxides are manganese thermite (MnO2)‚ Cr2O3‚ and copper thermite (CuO). Aluminum can also be replaced by any reactive metal. Aluminum
