Hematite - Wikipedia
Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite forms in the shape of crystals through the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.Hematite and ilmenite form a complete solid solution at temperatures above 950 °C (1,740 °F).
Hematite - an overview | ScienceDirect Topics
The O1s peak of hematite is characterized by a band at 529.9 eV corresponding to the oxide ion, with a small contribution at 532 eV corresponding to the hydroxyl ions or adsorbed water. This spectrum is consistent with previous works on hematite [ 38, 39 ].
