Thnx
Reduction of metal oxides with aluminum powder in which a huge amount of heat is liberated is called thermite process. APPLICATIONThermite process is very useful for the welding of broken metal parts. When Aluminum powder reacts with iron oxide or chromium oxide, a large amount of heat is released and about a temperature of 3500oC is attained which is enough to weld broken metallic parts.2Al + Fe2O3 = Al2O3 + 2Fe2Al + Cr2O3 = Al2O3 + 2Cr

Reduction of metal oxide to form metal by usiusig AL powder as a reducing agent
Sorry iron oxide and aluminum.
A highly exothermic reaction between iron and aluminum oxide to produce molten iron

Reactions which are carried out by heat is called thermit reactions.For e.g. CaCo3 when heated we get CaO+CO2

Fe2O3 +2Al ?Al2O3 +2Fe+heat and energy
This rexn is used for joining railways Tract and crack part in machine In iron metal produce here in molten stage

The reaction of iron oxide with aluminum is used to join railway tracks or cracked machine parts. This reaction is known as thermit reaction.

When aluminium is react with ferrous oxide then aluminium oxide with energy and iron (in melted form ) are formed this is known as thermite reaction
Thank you…
Aluminothermy is also known as thermite reaction. Reaction of aluminium metal with ferric oxide is only the thermite reaction. It exerta a lot of heat during this reaction.
The process of igniting Aluminium and Ferric oxide is called thermite reaction. This is an exothermic reaction. Iron obtained in this process is in molten state. Fe₂O₃ (s) + Al (s) →Al₂O₃ + 2 Fe(l) + Heat Thermite reaction used for the welding of rails (joining metals) called as thermite welding.
