Magnetite: 72% pure iron. 2.
In an iron-rich material, each carbon atom bonds with three iron atoms to form iron carbide, Fe 3 C, also called cementite. Iron carbide is 6.7% carbon by weight. Thus, on the phase diagram, a carbon weight of 6.7% corresponds to iron carbide. A complete iron–carbon phase diagram should extend to carbon.
