Iron ball paint (paint based on Iron Carbonyl ) is a type of paint used for Stealth surface coating. The paint absorbs RF energy in the particular wavelength used by primary RADAR. Its Chemical Formula is C5FeO5 / Fe(CO)5, with a Molecular Mass of 195.9 g/mol and an apparent Density of 76.87 g/cmc. The Molecular Structure consists of an Iron atom surrounded by 5 Carbon Monoxide structures (it takes a ball-like shape, hence the name). Its Melting Point is 1536° C. Iron ball paint has a Hardness of 82-100 HB. The paint is obtained by carbonyl decomposition process and may have traces of Carbon , Oxygen and Nitrogen . Iron carbonyl is also used as a Catalyst and in medicine as an iron suppliment, even though it is toxic. The painting of the F-117 is done by industrial robots with the plane covered in tiles glued to the fuselage and the remaining gaps filled with iron ball paint. This type of coating converts the radar wave energy into heat (by molecular Oscillation s). The heat is then transferred to the aircraft and dissipated. It is the same principle by which water is heated in the Microwave Oven . SEE ALSO EXTERNAL LINKS |
