In thermite process, thermite mixture is:
Open in App
Solution
The correct option is A Al powder + Oxide
Alumino thermite Process: is a process of Extracting metals by reduction of a metal oxide to form metal using aluminium powder , the Al acts as a reduaing agent. It is an Exothermic Process which liberate large amount of heat. This method can be used to reduce all the metallic oxides, with oxide of magnesium being the only exception.
Example:- Reduction of Ferrous oxide to Ferrious metal, Iron (III) oxide is mixed with Aluminium powder.
Fe2O3+2Al⟶2Fe+Al2O3+Heat
