What is Thermite?

Thermite is a mixture of a reducing agent, typically aluminum powder, and an oxide of a more reactive metal, such as iron oxide (rust). When ignited, the thermite reaction takes place, producing molten iron and aluminum oxide along with a substantial amount of heat. This reaction is highly exothermic, reaching temperatures of around 2500 degrees Celsius (4500 degrees Fahrenheit).

Composition of Thermite

The primary components of thermite include:

• Metal Oxide: Commonly iron(III) oxide (Fe2O3), but other metal oxides can also be used.
• Metal Powder: Aluminum powder is the most frequently used reducing agent.

The stoichiometric ratio of these components is crucial for the thermite reaction to proceed efficiently.

Table: Common Thermite Compositions

Metal Oxide	Reducing Agent	Reaction Product
Iron(III) Oxide (Fe2O3)	Aluminum Powder (Al)	Iron (Fe) + Aluminum Oxide (Al2O3)
Chromium(III) Oxide (Cr2O3)	Aluminum Powder (Al)	Chromium (Cr) + Aluminum Oxide (Al2O3)
