iron
Molecular formula: FE
molecular weight: 55.845
CAS:

density: 7.86
melting point: 1535 ° C
boiling point: About 2,800 ° C
traits: silver-gray metal, firm consistency, scalability good.
solution: dissolve in sulfuric acid, hydrochloric acid and dilute nitric acid.
uses: Iron is an essential industrial metals. Iron can be used for motor-generators and Core, reduction of iron powder can be used for powder metallurgy, steel, iron alloy with a small amount of carbon, widely used in the manufacture of machinery and tools.
preparation or sources: Iron is important magnetite, hematite, limonite, and siderite. High purity iron from iron oxide reduction with hydrogen derived. Industrial Rail will be iron ore, coke and flux (limestone) on the result of blast furnace smelting.
