Hydroxy pure Iron metal (Fe)-Powder

Iron is a metal element with an atomic number of 26. The chemical formula of iron is Fe, and its English name is iron. The average relative atomic mass is 55.845. Pure iron is white or silvery white with metallic luster. Melting point 1538℃, boiling point 2750℃, soluble in strong acid and medium strong acid, insoluble in water. Iron has 0, +2, +3, +4, +5, and +6 prices, of which +2 and +3 prices are more common, and +4, +5, and +6 prices are rare.

Iron is widely distributed in life, accounting for 4.75% of the earth's crust content, second only to oxygen, silicon, and aluminum, and ranking fourth in the earth's crust content. Pure iron is a flexible and malleable silver-white metal. It is used to make iron cores for generators and motors. Iron and its compounds are also used to make magnets, medicines, inks, pigments, abrasives, etc. It is what the industry says One of the "ferrous metals" (the other two are chromium and manganese) (in fact, pure pig iron is silvery white. The iron element is called "ferrous metal" because the surface of iron is often covered with a layer of black tetroxide. Three-iron protective film) [1]. In addition, the human body also contains iron, and the +2 valent ferrous ion is an important component of hemoglobin, which is used for the transportation of oxygen.

The main iron ore used are: Fe2O3 (hematite), Fe3O4 (magnetite), FeCO3 (siderite), FeS2 (pyrite)...

Pure metals are generally solid at room temperature (except for mercury), with metallic luster (that is, strong reflection of visible light), most of which are excellent conductors of electricity and heat, ductility, high density, and high melting point. [1] Metal resources on the earth are widely present in the crust and ocean. Except for a few very inactive metals such as gold and silver, which exist in elemental forms, the rest are in the form of compounds. [1] Metals are widely present in nature, and are extremely common in daily life. They are very important and most used in modern industry.
