${\mathrm{Fe}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)+2\mathrm{Al}\left(\mathrm{s}\right)\to 2\mathrm{Fe}\left(\mathrm{l}\right)+{\mathrm{Al}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)+\mathrm{Heat}$, in the reaction iron oxide is being reduced to iron metal. What is the name given to this specific reaction?

${\mathrm{Fe}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)+2\mathrm{Al}\left(\mathrm{s}\right)\to 2\mathrm{Fe}\left(\mathrm{l}\right)+{\mathrm{Al}}_2{\mathrm{O}}_3\left(\mathrm{s}\right)+\mathrm{Heat}$, this reaction is an example of a reaction in which metal oxide is being reduced to metal. Here, iron oxide is being reduced to iron metal in the presence of aluminum powder. This reduction has a very interesting application. It is often used for joining railway tracks or repairing damaged machinery due to its high temperature output and ability to fuse metals together. That's why this reaction has been given a special name "Thermite reaction".
