• 개요

  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.

• 화학적 성질

• 잠재적 노출

  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.

• 비 호환성

  Contact with hydrogen peroxide, ethyl ene oxide, calcium hypochlorite will cause explosion. Violent reaction with powdered aluminum; hydrazine, hydrogen trisulfide.
