Magnetite Applications and Uses
Magnetite is the primary source material for this. Ground magnetite is partially reduced, relieving it of some of its oxygen, leaving a catalyst bearing a magnetite core with an outer shell of ferrous oxide (FeO, würstite). The advantage of this catalyst comes in its porosity, and thus it is a highly active, high surface area material.
