Fe2O3ssa

Fe2O3ssa is not a recognized chemical species in standard nomenclature or literature. The string appears to be a nonstandard or erroneous label, potentially a typographical error, a dataset code, or a misnomer connected to iron(III) oxide, Fe2O3. Consequently, there is no established compound by the name Fe2O3ssa. When encountered, it is common to interpret the reference as Fe2O3, known as hematite, or as a mixture that contains Fe2O3.

Iron(III) oxide, Fe2O3, commonly known as hematite, is an oxide of iron in which iron is in the +3 oxidation state. Hematite crystallizes in a hexagonal close-packed lattice related to the corundum structure, with iron in octahedral coordination to oxygen. The pure phase is typically red to reddish-brown in color and serves as one of the most important iron ores. At room temperature hematite exhibits weak ferromagnetism due to spin canting and shows a Morin transition near 260 kelvin, below which it becomes antiferromagnetic.

Occurrence and production: Hematite is widely distributed in the Earth's crust and is a primary iron ore mined in many regions worldwide. It forms through sedimentary, hydrothermal, and metamorphic processes. In mining operations, hematite ore is crushed and processed to produce concentrates, which are then smelted or reduced to extract metallic iron.

Applications and properties: Hematite is used as an industrial pigment (red iron oxide), in ceramics, and as a catalyst support and magnetic material in certain contexts. It is insoluble in water, stable under typical environmental conditions, and has high density. If Fe2O3ssa appears in a data source, verification against a standard chemical identifier is recommended.
