WebMay 16, 2024 · The most common example of an aluminothermic reaction is thermite, in which powdered aluminum reacts with an iron oxide. Because aluminum has a greater affinity for oxygen than iron, oxygen is transferred from the iron oxide to the aluminum, releasing a great deal of energy and leaving behind molten iron and aluminum oxide. WebAug 14, 2024 · When welding, the ends of the two rails are fixed in the mold in advance, and then the mixture of aluminum powder and iron oxide powder (called thermite) is heated in the crucible. An exothermic reaction is producing liquid metal (Iron) and molten slag which are injected into the mold.
