Thermite Reaction: aluminum reacts with iron(III) oxide

2021-5-23  The reaction of iron (III) oxide and aluminum is initiated by heat released from a small amount "starter mixture". This reaction is an oxidation-reduction reaction, a single replacement reaction, producing great quantities of heat (flame and sparks) and a stream of molten iron and aluminum oxide which pours out of a hole in the bottom of the pot into sand.

The process of extracting the metal by fusion of its oxide ore with carbon (C) or CO is called smelting. It is known as alumino-thermic reduction or Gold Schmidt thermite process. (oxidation of the reducing agent and reduction of the metal oxide), negative. During reduction, the oxide of a metal decomposes:

Thermite temperature, oxygen balanced iron thermite 2al

A thermite reaction--sometimes called a Goldschmidt reaction--refers to the very exothermic process occurring between a metal oxide such as Iron (III) oxide. Thermite is a material used in welding to melt metals together. It's a mixture of metallic aluminum and iron oxide (ferric oxide), which produces molten iron after a redox reaction.
