The first wrought Iron used by mankind during prehistory came from meteors. The smelting of iron in bloomeries began in the second millennium BC. Artefacts from smelted iron occur in India from 1800-1200 BC.in the Levant from about 1500 BC.
Cast Iron was first produced in China about 550 BC, but not in Europe until the medieval period.
Reported in EPA TSCA Inventory.
For occupational chemical analysis use NIOSH: Elements (ICP), 7300; Metals in Urine (ICP), 8310.
The IUPAC name of this chemical is Iron. With the CAS registry number 7439-89-6 and EINECS registry number 231-096-4, it is also named as Iron, elemental. In addition, the molecular formula is Fe and the molecular weight is 55.85. It is a kind of and belongs to the classes of Inorganics; Alphabetic; Analytical Standards; Application CRMs; ICertified Reference Materials (CRMs); Industrial Raw MaterialsReference/Calibration Standards; IRMM/BCR Certified Reference Materials; Matrix CRMs; Reactor DosimetryCertified Reference Materials (CRMs); Reactor Neutron Dosimetry; Reactor Neutron DosimetryCertified Reference Materials (CRMs).
Preparation of Iron: it can be prepared by iron hydroxide or iron oxide with hydrogen. It is a kind of reduction reaction. The equations are as follows: 2Fe(OH)3 + 3H2 → 2Fe + 6H2O; Fe2O3 + 3H2 → 2Fe + 3H2O. Also it can be get by oxalic acidiron and ammonia. The reaction temperature is 400-500 °C. You should get the oxalic acidiron from sulfuric acidiron and sodium oxalate at first.
Uses of Iron: it can react with water to get iron oxide. The equations are as follows: Fe + H2O → FeO + H2; 2Fe + 3H2O → Fe2O3 + 3H2; 3Fe + 4H2O → Fe3O4 + 4H2. And it reacts with oxygen in the air to form various oxide and hydroxide compounds; the most common are iron(II,III) oxide (Fe3O4), and iron(III) oxide (Fe2O3). In addition, it is used as gel, catalyst, absorbent, reductant and sintering surfactant. Also it can be used for powder metallurgy products, mechanical parts products and hard alloy material products. Moreover, it can be used in preparation of magnets, drugs, ink, paint and abrasive.
