APPLICATIONS
|
- Acts as a pigment in paints, coatings, and colored
concretes, used in thermalite. Is a low cost, nontoxic, environmental
friendly catalyst for various reactions such as oxidation of carbon monoxide,
reduction of nitrogen oxides and sulfur dioxide by CO, photocatalytic
splitting of water, Fischer-Tropsch synthesis of hydrocarbons, catalytic
decomposition of industrial dyes, water-gas shift reactions, nucleation of
diamonds, conversion of phenolic and other environmentally harmful aromatic
compounds, dehydrogenation of ethylbenzene to styrene, and catalytic
oxidations of various organic compounds. It is used in magnetic storage
devices and in the production of iron, steel and alloys. It functions as a
catalyst in the chemical oxidation of hydrogen peroxide used for the
treatment of contaminated water with hydrogen peroxide. It is a highly stable
n-type semiconductor and possesses a band gap of 2.0 to 2.2eV. It is widely
used in solar photo electrolysis cells. Self-organized nano porous iron(III)
oxide (hematite) has been prepared. Orientation effects on nearly opaque
single crystals of iron(III) oxide have been investigated by laser Raman
spectroscopy. Used in the preparation of iron(III) oxide-hydrate gels. Also has
many applications, mainly used in iron industry, pigment, as photocatalyst,
medicine and polishing jewels.
