Define aluminothermic reaction |
| Answer» Thermite is a pyrotechnic composition of aluminium powder and a metal oxide. It produces an aluminothermic reaction known as a thermite reaction.The reaction of iron (III) oxide and aluminum can be represented by the equation:Fe2O3 (s) + 2 Al (s) → Al2O3 (s) + 2 Fe (s)This reaction is known as the “thermite” process, which has been used industrially for welding that is the preparation of metals from their oxides, and the production of incendiary devices. The process is initiated by heat, but then becomes self-sustaining. | |
