General description

Iron(III) oxide nanopowder is a fine powder with a particle size of less than 50 nm. It is a red or black solid compound made up of iron and oxygen. It is also known as hematite or ferric oxide. It is a naturally occurring mineral that can also be synthesized in the laboratory. Iron(III) oxide has a number of useful physical properties. It has a high refractive index and is opaque, making it useful as a pigment in paints in inks. Iron(III) oxide is also catalytically active and weakly ferromagnetic at room temperature.

Application

Iron(III) oxide nanopowder has a number of uses due to its magnetic and catalytic properties. It is used in the production of magnetic recording media such as magnetic tapes and disks. It is also used as a catalyst in the production of chemicals, including the production of gasoline and plastics and in environmental remediation.
