What is the thermite process? Mention it’s applications in daily life?
1) The thermite process involves the reaction of metal oxides with Aluminum.
2) When highly reactive metals such as sodium (Na), calcium (Ca) aluminum (Al) are used as reducing agents, they haver the tendêncy to displace the metals of lower reactivity from the compound.
3) These displacement reactions are highly exothermic. The amount of heat evolved is so large that metals produced in this reaction would be in a molten state.
Applications of thermite process:
1) The reaction of Iron Oxide (Fe2O3) with aluminum is used to join railings of railway tracks or to join cracked machine parts.
2) It is also used for joining of the cracked metal utensils in the house.
