Aluminum Reacting with Iron(III) Oxide (Thermite)

2Al + Fe₂O₃ → Al₂O₃ + 2Fe

نظرة عامة

The thermite reaction involves aluminum reducing iron(III) oxide to produce aluminum oxide and molten iron. This spectacularly exothermic reaction generates temperatures exceeding 2500 C, hot enough to melt iron. Once ignited (requires about 1500 C), it cannot be extinguished with water.
