Beschreibung
Iron(III) oxide is known in mineral form as hematite, which is the primary form of iron ore.
It is also known simply as iron oxide or ferric oxide and is what is colloquially called rust
when referring to the corrosion of iron objects.
Iron (III) oxide exists in mineral form as hematite.It is 70% iron and is the primary source
of iron ore in the world. About 90% of the iron mined in the United States is hematite. World
production of this ore is more than 1 billion tons. Magnetite and taconite are two other
primary iron oxide minerals used as iron ore.The name hematite comes from the blood-red
color of powdered hematite.
Chemische Eigenschaften
Hematite is a noncombustible, black to black red or brick-red mineral (iron ore) composed mainly of
ferric oxide, Fe2O3. Ferric oxide

Hazard
Benign pneumoconiosis.
m?gliche Exposition
Hematite; as an iron ore composed
mainly of ferric oxide, is a major source of iron and is used
as a pigment for rubber, paints, paper, linoleum, ceramics,
dental restoratives; and as a polishing agent for glass and pre cious metals. It is also used in electrical resistors, semiconduc tors, magnets, and as a catalyst. Human exposure to hematite
from underground hematite mining is principally through
inhalation and/or ingestion of dusts. No estimates are available
concerning the number of underground miners exposed.
Structure and conformation
α-Fe2O3, hematite [1317-60-8], has a corundum structure with color
changes from light red to dark violet with increasing particle size.
Inkompatibilit?ten
Contact with hydrogen peroxide, ethyl ene oxide, calcium hypochlorite will cause explosion.
Violent reaction with powdered aluminum; hydrazine,
hydrogen trisulfide.
