- 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. Its chemical formula is Fe2O3. The
mineral form of ferric oxide is hematite; it is mined as the main ore of
iron.
- Goethite and hematite
are the most thermodynamically stable ferric oxides in oxic soils and
sediments, and their ratio depends primarily on
the parent minerals
and on the activity of water during their formation. In soils, the
transformation rate of ferric oxide due to seasonal cycling, and the
reducing and complexing activity of organic substances are important
parameters.
- Fe2O3 is very affected
by a reducing atmosphere where it can act as a flux in both bodies and
glazes at high temperatures. Its fluxing action in reduction is quite
remarkable and can be demonstrated using a line blend in a clear glaze.
Higher amounts of iron exhibit dramatically increased fluidity.
- Fe2O3 is the most
natural state of iron oxide where it is combined with the maximum amount
of oxygen. In oxidation firing it remains in this form to typically
produce amber to yellow up to 4% in glazes (especially with lead and
calcia), tans around 6% and browns in greater amounts. In the 20% range,
matteness is typical. However, once it reduces to FeO and immediately
begins fluxing and forming a glass, it is difficult to reoxidize. Since
the breakdown of carbon or sulfur compounds in body and glaze so easily
reduces iron, a slow and very thoroughly oxidizing atmosphere is
critical through the 700-900C range to assure that all the iron remains
in its antiflux oxidized form.
- Ferric oxides are often
added to coatings and foundry moulding materials in order to suppress
casting defects like pinholes. By the delivery of oxygen with
T>1200°C free hydrogen and nitrogen can be bind. Castings defects
resulting from thermal expansion are reduced by the addition of ferric
oxide to the moulding material, because the thermal expansion of the
moulding material is reduced.
- A very fine powder of
ferric oxide is known as jeweller's rouge, red rouge, or simply rouge.
It is used to put the final polish on metallic jewellery and lenses, and
historically as a cosmetic. Iron oxide yellow is widely used in
painting, scagliola and concrete due to its bright and pure color, good
weather proof and high opacity, also can be used as colorant for ink,
rubber, paper and so on.
- Based on statistics of
four branches of the China Dyestuff Industry Association, on titanium
white powder, lithopone powder, ferric oxide and lemon chrome in 2005,
there were 239 enterprises producing the above four types of inorganic
pigment, with a combined production capacity of 1.893 million tons and
output of 1.5583 million tons, of which 44% was titanium white powder,
40% was ferric oxide, 14% was lithopone powder, and 2% was chrome family
pigment. Total import of the four was 420,000 tons in 2005, and the
total export was 580,000 tons, and their apparent consumption was 1.39
million tons, accounting for 23% of the total consumption of the same
kinds of inorganic pigment in the world.
- China's total import of
titanium white powder was 228,000 tons in 2005, including 76,000 tons
imported by processing trade and as transit goods through bonded
warehouses, and export of titanium white powder was 155,000 tons. The
proportion of import by processing trade will remain at more than 50%,
while the export will continue increasing.
