Meaning and Definition
A metallurgical process for producing high temperatures or reducing metals from their oxides using powdered aluminium as a reducing agent.
A chemical reaction in which aluminium powder reacts with a metal oxide, releasing intense heat and producing alumina and the pure metal; also known as the thermite process. In a broader sense, it refers to any industrial or laboratory technique based on this exothermic reduction reaction.

FAQ
Frequently Asked Questions
Essentially, yes. 'Aluminothermy' is the technical name for the process, while 'thermite reaction' often refers to the specific instance using iron oxide, popularised in demonstrations and some industrial applications.
Metals whose oxides are less stable than aluminium oxide. This includes chromium, manganese, vanadium, and, in the classic 'thermite' example, iron.
Yes. It is a highly exothermic, self-sustaining reaction that can produce temperatures exceeding 2500°C. It should only be conducted by trained personnel with proper safety equipment.
Its primary uses are in thermite welding (e.g., for joining railway tracks or heavy cables) and in the production of certain pure, carbon-free metals and alloys.
A metallurgical process for producing high temperatures or reducing metals from their oxides using powdered aluminium as a reducing agent.
Aluminothermy is usually technical / scientific in register.
Aluminothermy: in British English it is pronounced /əˌluː.mɪ.nəʊˈθɜː.mi/, and in American English it is pronounced /əˌlu.mə.noʊˈθɝː.mi/. Tap the audio buttons above to hear it.

Mnemonic
Think of ALUMINium providing the THERMal energy for cheMISTRY = ALUMINOTHERMY.
Conceptual Metaphor
METAL PRODUCTION IS A FIERY EXCHANGE (e.g., aluminium 'trades' its chemical energy for the pure metal).
