Question

what is thermide process

Answer 1

Reduction of metal oxides with aluminum powder in which a huge amount of heat is liberated is called thermite process. 

APPLICATION

 

Thermite process is very useful for the welding of broken metal parts. When Aluminum powder reacts with iron oxide or chromium oxide, a large amount of heat is released and about a temperature of 3500oC is attained which is enough to weld broken metallic parts.   

2Al + Fe2O3  Al2O3 + 2Fe
2Al + Cr2O3  Al2O3 + 2Cr
