Iron oxide

Iron oxides are chemical compounds composed of iron and oxygen. All together, there are sixteen known iron oxides and oxyhydroxides.

Iron oxides and oxide-hydroxides are widespread in nature, play an important role in many geological and biological processes, and are widely used by humans, e.g., as iron ores, pigments, catalysts, in thermite (see the diagram) and hemoglobin. Common rust is a form of iron(III) oxide. Iron oxides are widely used as inexpensive, durable pigments in paints, coatings and colored concretes. Colors commonly available are in the "earthy" end of the yellow/orange/red/brown/black range. When used as a food coloring, it has E number E172.

Oxides

Iron(II) oxide

Iron(II) oxide is the inorganic compound with the formula FeO. Its mineral form is known as wüstite. One of several iron oxides, it is a black-colored powder that is sometimes confused with rust, which consists of hydrated iron(III) oxide (ferric oxide). Iron(II) oxide also refers to a family of related non-stoichiometric compounds, which are typically iron deficient with compositions ranging from Fe_0.84O to Fe_0.95O.

Preparation

FeO can be prepared by the thermal decomposition of iron(II) oxalate.

The procedure is conducted under an inert atmosphere to avoid the formation of ferric oxide. A similar procedure can also be used for the synthesis of manganous oxide and stannous oxide.

Stoichiometric FeO can be prepared by heating Fe_0.95O with metallic iron at 770 °C and 36 kbar.

Reactions

FeO is thermodynamically unstable below 575 °C, tending to disproportionate to metal and Fe₃O₄:

Structure

Iron(II) oxide adopts the cubic, rock salt structure, where iron atoms are octahedrally coordinated by oxygen atoms and the oxygen atoms octahedrally coordinated by iron atoms. The non-stoichiometry occurs because of the ease of oxidation of Fe^II to Fe^III effectively replacing a small portion of Fe^II with two thirds their number of Fe^III, which take up tetrahedral positions in the close packed oxide lattice.

LiveJournal

LiveJournal / LJ or Zhivoy Zhurnal (Russian: Живой Журнал)/ZheZhe (Russian: ЖЖ) in Russia, is a social networking service based in San Francisco, California, where Internet users can keep a blog, journal or diary. A wide variety of political pundits also use the service for political commentary, particularly in Russia, where it partners with the online newspaper Gazeta.ru. As with many other social networks, a wide variety of public figures use the network.

LiveJournal was started on April 15, 1999 by American programmer Brad Fitzpatrick as a way of keeping his high school friends updated on his activities. In January 2005, blogging software company Six Apart purchased Danga Interactive, the company that operated LiveJournal, from Fitzpatrick. Six Apart sold LiveJournal to Russian media company SUP Media in 2007, but continued to develop the site by the San Francisco-based company LiveJournal, Inc. In January 2009 LiveJournal laid off some employees and moved product development and design functions to Russia.

Beyond the Black Stump (comic strip)

Beyond the Black Stump is an Australian comic strip written by Sean Leahy. It debuted in 1988 and won the "Best Comic Strip" at the 2003 National Coffs Harbour Cartoon Awards and the "Comic Strip Cartoonist of the Year" at the Australian Cartoonist's Association's Stanley Award the same year.

The strip follows a cast of Australian wildlife who deal with the day-to-day stresses of marriage, parenting and friendship.
