A process which exploits the exothermic characteristics of finely-divided aluminium and/or ferro-silicon to generate high temperatures on combustion. Used in the production of some refractory metals and ferro-alloys, also for welding. See also Thermit.
aluminothermy, aluminothermics A process by means of which high temperatures are produced by the combination of aluminium and oxygen.
a process of producing high temperatures by causing finely divided aluminum to react with the oxygen from another metallic oxide.
