Hematite , also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2O 3. It has the same crystal structure as corundum (Al 2O 3) and ilmenite (FeTiO 3). With this it forms a complete solid solution at temperatures above 950 °C (1… Web18 okt. 2024 · The solubility of such species was reported to be an important factor in the transition from magnetite to hematite under similar hydrothermal conditions. 17 Simultaneously, maghemite dissolves in the solution to also produce Fe(OH) 3 (aq) which then reprecipitates to form hematite, resulting in the coexistence of three phases.
