Question

what is thermite reaction?​

Answer 1

The thermite reaction is an exothermic reaction between the metal and metal oxide. For example the reaction between the aluminium with the metal oxides, where aluminium acts as a reducing agent. The aluminium reduces the metal oxide most probably an iron (lll) oxide to produce ferrous and aluminium oxide. During the reaction, large amount of energy is released.

Example:-

Fe2O3 + 2Al → 2Fe + Al2O3 + heat

Use of the thermite reaction:

• The reaction is used for thermite welding.
• The reaction is used to connect railway tracks.
• The reaction also used in the demolition of ammunitions and metal refining.

Answer 2

Answer:

Thermite is a pyrotechnic composition of metal powder and metal oxide. When ignited by heat, thermite undergoes an exothermic reduction-oxidation reaction. Most varieties are not explosive, but can create brief bursts of heat and high temperature in a small area.
