Metal Powder

Iron powder is a lustrous, ductile, malleable and silver-gray metal. It is well known to exist in four distinct crystalline forms. Iron rusts in the presence of damp air, but not in dry air. It dissolves readily in dilute acids. Iron is chemically active and forms two vital series of chemical compounds, the bivalent iron (II), or ferrous, compounds and the trivalent iron (III) or ferric, compounds.

Iron powder is the most utilized of all the metals. This is produced in tons of all the metal worldwide. It has low cost and high strength so that’s why it is indispensable. It has applications from food containers to family cars, from screwdrivers to washing machines, from cargo ships to paper staples.

Iron powder: Steel is the best-known alloy of iron, and some of the forms that iron takes involve: pig iron, wrought iron, cast iron, carbon steel, alloy steels, and iron oxides. Most are utilized to synthesize steel, employed in civil engineering (reinforced concrete, girders, etc) and in manufacturing. Cast iron comprises 3–5% carbon. It is utilized for pipes, valves, and pumps. It is not as tough as steel however it is cheaper. Magnets can be manufactured of iron and its alloys and compounds.

Iron powder utilized as catalysts in the Haber process for producing ammonia, and in the Fischer–Tropsch process for converting syngas (hydrogen and carbon monoxide) into liquid fuels. Ferrous oxide is a greenish to black powder applied primarily as a pigment for glasses. It is employed to make iron alums and other ferric compounds. It is utilized as a coagulant in water purification and sewage treatment, and as a mordant (fixative) in textile dyeing and printing.

The finely powdered red form, often called jewelers’ rouge, is employed for polishing precious metals and diamonds, as well as in cosmetics. Iron powder is also used as a pigment and a polishing agent. Iron serves as a starting material for the manufacture of various other ferrous compounds and it is also applied as a reducing agent. It is also employed in making inks, fertilizers, and pesticides and for iron electroplating.
