The Element Iron

What is your name? From Anglo - Saxon iron. Chemical symbols from Latin in iron and iron

Archaeological evidence indicates that people are using iron for at least 5000 years. Iron occupies about 6% of the earth's crust, which is the most expensive, is also one of the most abundant of all metallic irons, and occupied most of the earth's core. Main hematite from hematite (Fe 2 O 3) and magnetite (Fe 3 O 4). Mineral taconite, limonite ((OH) · nH 2 O of FeO) and siderite (FeCO 3) are other important sources

Iron alloy for the manufacture of steel, iron and a large number of carbon. Typically, steel contains 0.3% at 5% carbon, depending on the properties required. Add other elements that can confer other useful properties of steel. Chromium can improve durability against a small amount of rust (stainless steel), nickel improves durability, heat resistance and acid; manganese increases strength, abrasion resistance, Mo increases strength and heat resistance Let it maintain high temperature, increase hardness tungsten, and vanadium strength and elasticity. Steel for the production of paper clips during all things, between the two sides and high-rise buildings

In addition to helping us build the world around us, iron also helps to maintain the vitality of plants and animals. Iron is an important component of hemoglobin oxygen species that is produced in the chlorophyll function of plants and is hemoglobin, supported in erythrocytes. Iron sulphate (of FeSO 4) for treating anemia of blood disorders

Carbonyl iron is highly refined. This is not a specific size of the iron particles, iron, but different from other elements of the iron powder in the manufacturing process. Carbonyl iron powder is generally most of all bioavailability compared with ferrous sulfate, which is considered to be about 75% bioavailable. Carbonyl requires stomach acid to dissolve to be absorbed, which makes it very weak, to the negative effect of food. In particular, wheat appears to reduce its absorption. This means that it is necessary for slow release to gastric acid naturally, making it very safe and converting to stomach side effects

Iron is the most abundant metal and is considered to be the tenth most abundant element on Earth. Iron also constitutes the most abundant (mass, 34.6%) element of the earth. The concentration of iron in the core is found mainly in the housing of about 5%. Iron ore, metal, free state is extracted from most elements. In order to obtain the elemental iron, impurities must be removed by chemical reduction. Iron is also used for the production of steel. The element is not the number of nonmetallic compositions such as steel, different metal alloys and carbon

Iron is probably the most precious metal, as humans are sure to miss this element over any other metal. When iron is rare, in the early 14th century, Edward III some iron cookware is classified as jewelry, accessories, iron hunting for robbery preferentially. The name "Iron" comes from "iarn" in Scandinavia. There are many wonderful stories about the source of iron. Some of them think iron is a gift from God, others try to explain it as a source from meteor. However, if we believe that iron can be reduced from some of the natural ore, this explanation is not necessary. When the fire lasts long enough, iron is first produced when some ore used to cook the fire is reduced. After this, I found that the higher the temperature (and the wind), the more the amount of iron will be. This method has been improved by several techniques up to the formation of the furnace
