Answer 1

Answer:

In engineering, the thermite process isused to weld railway tracks together. A mixture of aluminium grit and iron(II, III) oxide is added to the apparatus and lit with an ignition rod. Liquid iron and aluminium oxide form in a very exothermic reaction.

Answer 2

Question:-

Where is thermite process used and why?

AnSWer:-

Thermite process is mainly used in broken rails, broken machine parts etc can welded without removing them from their original sites.

❐ When the mixture is ignited, ferric oxide is reduced to metallic iron by aluminium. Because of evolution is large amount of heat, temperature rises to ~ 25000°c.

The molten iron thus produced is allowed to fall on the red hot broken ends of iron pieces and joins them together.
