Where does iron come from?

The word ferrum itself possibly comes from the Semitic languages, via Etruscan, from a root that also gave rise to Old English bræs " brass ". The English word iron derives ultimately from Proto-Germanic *isarnan, which is also the source of the German name Eisen and Dutch ijzeren. It was most likely borrowed from Celtic *isarnon, which ultimately comes from Proto-Indo-European * is- (e)ro- "powerful, holy" and finally * eis "strong", referencing iron's strength as a metal. Kluge relates *isarnon to Illyric and Latin ira, 'wrath'). The Balto-Slavic names for iron (e.g. Russian железо [ zhelezo ], Polish żelazo, Lithuanian geležis) are the only ones to come directly from the Proto-Indo-European *ghelgh- "iron". In many of these languages, the word for iron may also be used to denote other objects made of iron or steel, or figuratively because of the hardness and strength of the metal. The Chinese tiě ( traditional 鐵; simplified 铁) derives from Proto-Sino-Tibetan *hliek, and was borrowed into Japanese as 鉄 tetsu, which also has the native reading kurogane "black metal" (similar to how iron is referenced in the English word blacksmith ).

What is the atomic number of iron?

Iron ( / ˈaɪərn /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table.

How does the body regulate iron?

Iron uptake is tightly regulated by the human body, which has no regulated physiological means of excreting iron. Only small amounts of iron are lost daily due to mucosal and skin epithelial cell sloughing, so control of iron levels is primarily accomplished by regulating uptake. Regulation of iron uptake is impaired in some people as a result of a genetic defect that maps to the HLA-H gene region on chromosome 6 and leads to abnormally low levels of hepcidin, a key regulator of the entry of iron into the circulatory system in mammals. In these people, excessive iron intake can result in iron overload disorders, known medically as hemochromatosis. Many people have an undiagnosed genetic susceptibility to iron overload, and are not aware of a family history of the problem. For this reason, people should not take iron supplements unless they suffer from iron deficiency and have consulted a doctor. Hemochromatosis is estimated to be the cause of 0.3 to 0.8% of all metabolic diseases of Caucasians.

What is the solution of ferropericlase?

Ferropericlase (Mg,Fe)O, a solid solution of periclase (MgO) and wüstite (FeO), makes up about 20% of the volume of the lower mantle of the Earth, which makes it the second most abundant mineral phase in that region after silicate perovskite (Mg,Fe)SiO#N#3; it also is the major host for iron in the lower mantle. At the bottom of the transition zone of the mantle, the reaction γ- (Mg,Fe)#N#2[SiO#N#4] ↔ (Mg,Fe) [SiO#N#3] + (Mg,Fe)O transforms γ-olivine into a mixture of silicate perovskite and ferropericlase and vice versa. In the literature, this mineral phase of the lower mantle is also often called magnesiowüstite. Silicate perovskite may form up to 93% of the lower mantle, and the magnesium iron form, (Mg,Fe)SiO#N#3, is considered to be the most abundant mineral in the Earth, making up 38% of its volume.

How is iron made?

For a few limited purposes when it is needed, pure iron is produced in the laboratory in small quantities by reducing the pure oxide or hydroxide with hydrogen, or forming iron pentacarbonyl and heating it to 250 °C so that it decomposes to form pure iron powder. Another method is electrolysis of ferrous chloride onto an iron cathode.

What are the oxidation states of iron?

What is the Iron Age?

The Iron Age is the final epoch of the three-age division of the prehistory and protohistory of humanity. It was preceded by the Bronze Age and the Stone Age ( Paleolithic, Mesolithic, Neolithic, and Chalcolithic ). The concept has been mostly applied to Europe and the Ancient Near East, but also, by analogy, to other parts of the Old World .

How did the Iron Age begin?

The "Iron Age" begins locally when the production of iron or steel has advanced to the point where iron tools and weapons replace their bronze equivalents in common use . For example, Tutankhamun's meteoric iron dagger comes from the Bronze Age. In the Ancient Near East, this transition took place in the wake of the so-called Bronze Age collapse, in the 12th century BC. The technology soon spread throughout the Mediterranean Basin region and to South Asia. Its further spread to Central Asia, Eastern Europe, and Central Europe is somewhat delayed, and Northern Europe was not reached until later, by about 500 BC.

What is the iron in Egyptian tombs?

The explanation of this would seem to be that the relics are in most cases the paraphernalia of tombs, the funeral vessels and vases, and iron being considered an impure metal by the ancient Egyptians it was never used in their manufacture of these or for any religious purposes. It was attributed to Seth, the spirit of evil who according to Egyptian tradition governed the central deserts of Africa. In the Black Pyramid of Abusir, dating before 2000 BC, Gaston Maspero found some pieces of iron. In the funeral text of Pepi I, the metal is mentioned. A sword bearing the name of pharaoh Merneptah as well as a battle axe with an iron blade and gold-decorated bronze shaft were both found in the excavation of Ugarit. A dagger with an iron blade found in Tutankhamun's tomb, 13th century BC, was recently examined and found to be of meteoric origin.

What is the melting point of iron?

Whilst terrestrial iron is naturally abundant, its high melting point of 1,538 °C (2,800 °F) placed it out of reach of common use until the end of the second millennium BC. Tin's low melting point of 231.9 °C (449.4 °F) and copper's relatively moderate melting point of 1,085 °C (1,985 °F) placed them within the capabilities of the Neolithic pottery kilns, which date back to 6000 BC and were able to produce temperatures greater than 900 °C (1,650 °F). In addition to specially designed furnaces, ancient iron production needed to develop complex procedures for the removal of impurities, the regulation of the admixture of carbon, and for hot-working to achieve a useful balance of hardness and strength in steel .

What is the name of the metal that was used in the Bronze Age?

Meteoric iron, a characteristic iron–nickel alloy, was used by various ancient peoples thousands of years before the Iron Age. Such iron, being in its native metallic state, required no smelting of ores. Smelted iron appears sporadically in the archeological record from the middle Bronze Age.

Can not getting enough iron cause anemia?

Low iron intake. Not getting enough iron in your diet can lead to anemia. Iron deficiency anemia can also develop if your body doesn’t absorb iron properly, which can happen with certain conditions, such as Crohn’s disease.

Overview

History

Iron is one of the elements undoubtedly known to the ancient world. It has been worked, or wrought, for millennia. However, iron objects of great age are much rarer than objects made of gold or silver due to the ease with which iron corrodes. The technology developed slowly, and even after the discovery of smelting it took many centuries for iron to replace bronze as the metal of choice for tools and weapons.
