Question
Write notes about the thermite process, and mention its application.
Answer
The thermite process is a highly exothermic reaction used for the production of pure metals or their alloys. In this process, a metal oxide is reduced by a more reactive metal, typically aluminium, which results in the production of pure metal and aluminium oxide as a byproduct. The reaction is initiated by heating the mixture of reactants to a high temperature, typically around 3000°C, using a suitable ignition source.
Application: It is also used in the welding industry for joining metal parts and in the pyrotechnic industry for producing various types of fireworks.
