Hematite Chemical Properties,Usage,Production
General Description
Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. It is the oldest known Fe oxide mineral and is widespread in rocks and soils. The name hematite is derived from the Greek word for blood α?μα haima, due to the red coloration found in some varieties of hematite.The red chalk writing of this mineral was one of the earliest in the history of humans.Rich deposits of hematite have been found on the island of Elba that have been mined since the time of the Etruscans.
Description
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.
Chemical Properties
Steel gray to black crystals or as ready earthy material.
Chemical Properties
Hematite is a noncombustible, black to black red or brick-red mineral (iron ore) composed mainly of ferric oxide, Fe2O3. Ferric oxide
Uses
Definition
Fe 2O3 with impurities.
Definition
A mineral form of iron(III) oxide. It is the principal ore of iron.
Definition
A mineral form ofiron(III) oxide, Fe2O3. It is the mostimportant ore of iron and usually occursin two main forms: as a massivered kidney-shaped ore (kidney ore)and as grey to black metallic crystalsknown as specular iron ore.Haematite is the major red colouringagent in rocks; the largest depositsare of sedimentary origin. Inindustry haematite is also used as apolishing agent (jeweller’s rouge) andin paints.
Hazard
Benign pneumoconiosis.
Flammability and Explosibility
Non flammable
Potential Exposure
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.
Incompatibilities
Contact with hydrogen peroxide, ethyl ene oxide, calcium hypochlorite will cause explosion. Violent reaction with powdered aluminum; hydrazine, hydrogen trisulfide.
