Magnetite is the primary oxide of iron found in meteorites (and thus presumably in asteroids). Thermite is a mixture of powdered magnetite and powdered aluminum. When ignited, the aluminum fuel burns using the magnetite as an oxidizer, resulting in much heat, aluminum oxide (corundum), and molten iron.
