- Iron(III) oxide —
also known as ferric oxide, Hematite, red iron oxide, synthetic
maghemite, colcothar, or simply rust — is one of several oxide compounds
of iron, and has paramagnetic properties.
- The mineral form of
ferric oxide is hematite; it is mined as the main ore of iron.
- Fe2O3 is very
affected by a reducing atmosphere where it can act as a flux in both
bodies and glazes at high temperatures.
- Fe3O4 can either be a
mix of FeO and Fe2O3 resulting from an incomplete conversion from one
type to the other, or it can be a completely different mineral form of
iron known as magnetic iron oxide from the ore magnetite.
- The preparation of a
pure ferric oxide nanoparticulate LB film, has a three-dimensional
ordered structure and good gas-sensing properties towards alcohols at
- Acicular gamma-iron(III)
oxide is manufactured by reacting an iron(II) salt solution with an
aqueous solution of an alkali metal hydroxide and oxidizing the
resulting suspension of iron(II) hydroxide in three stages.
- The preparation and
characterization of a ferric oxide nanoparticle–copper phthalocyanine
derivative hybrid LB film, a kind of one-dimensional superlattice, are
- Primarily used in the
final finish (colouring) of gold and silver, it is the finest of all
rouges. The abrasive is Ferric Oxide. It also produces an excellent
finish on brass.
- Iron(III) oxide is
often used in magnetic storage, for example in the magnetic layer of
floppy disks. These consist of a thin sheet of PET film, coated with
- Iron(III) oxide is
used in the production of pure iron in a blast furnace.
- A nanoparticulate
ultrathin film was constructed from alternate layers by the Langmuir–Blodgett
- One technique,
is based on freezing and thawing.It leads to the formation of dense
Hydrous ferric oxides(HFO) aggregates and improves the filtration and
- The production
capacity of ferric oxide in China exceeded 700 kiloton, the total output
to 622.7 kiloton and export volume to 329.5 kiloton. Ferric oxide
products are mainly exported to North America, Europe and Southeast
expansion of Chinas ferric oxide industry has not only drew wide
attention from relevant industries such as steel industry, smelting
industry, titanium industry and sulfuric acid industry, but also
attracted oversea manufacturers and sales companies.
for iron and iron oxide powder is estimated to be $756 million. Metallic
iron-base powder accounts for $373 million and iron oxide powders for
