Thermite is an energetic composition consisting of a metal powder and metal oxide.Thermites are a special type of single replacment reactions that do not take place in aqueous solution. They are capable of producing extreme heat, enough to melt or boil other metals. The products of this reaction are the oxide of the metal powder, and pure metal produced from the oxide.
· Fe 2 O 3 + 2Al → 2Fe + Al 2 O 3 + heat and light. Note the reaction is both an example of combustion and also an oxidation-reduction reaction. While one metal is oxidized, the metal oxide is reduced. The rate of the reaction can be increased by adding another source of oxygen. For example, performing the thermite reaction on a bed of dry ice ...
