Answer 1

$<marquee>ANSWER</marquee>$

★ A thermite reaction is basically iron oxide (rust) reacting with aluminum to produce molten iron. The products are aluminium oxide, elemental iron, and a large amount of heat. The reactants are commonly or thermite mixture is aluminum powder and iron oxide (rust) powder. When the mixture is heated, it starts reacting as the aluminum is more reactive than the iron and aluminium forms stronger and stable bonds with oxygen than iron.

Uses-

1.The reaction is used for thermite welding, often used to join rail tracks. 2.Thermites have extremely high temperature and also been used in metal refining, demolition of ammunitions, and in incendiary weapons.

3.Some thermite-like mixtures are used in fireworks.

4.A thermite reaction is used to purify the ores of some metals called as thermite process.

Answer 2

Answer:

It is used for Reduction of metal oxides  and it is done at a very high temperature and i.e. why used for metal having high melting point like tungsten .

I hope it helps .
