Thermite Reaction

2Al + Fe₂O₃ → Al₂O₃ + 2Fe

Genel Bakış

Aluminum reduces iron(III) oxide in this extremely exothermic redox reaction, reaching temperatures above 2500 C. Aluminum is oxidized from Al⁰ to Al³⁺ (losing 3 electrons) while iron is reduced from Fe³⁺ to Fe⁰. Once ignited, the reaction is self-sustaining and produces molten iron.
