Cementite - Wikipedia

Cementite (or iron carbide) is a compound of iron and carbon, more precisely an intermediate transition metal carbide with the formula Fe 3 C. By weight, it is 6.67% carbon and 93.3% iron. It has an orthorhombic crystal structure. It is a hard, brittle material, normally classified as a ceramic in its pure form, and is a frequently found and important constituent in ferrous metallurgy.

Hematite - Wikipedia

The magnetic structure of α-hematite was the subject of considerable discussion and debate in the 1950s because it appeared to be ferromagnetic with a Curie temperature of around 1,000 K (730 °C), but with an extremely tiny magnetic moment (0.002 µ B). Adding to the surprise was a transition with a decrease in temperature at around 260 K ...
