Scientific Analysis of Iron Pillar of Delhi

Iron Pillar in Delhi

Wrought iron pieces are believed to be used for constructing the Iron Pillar. According to a report published, the pillar is rust-free because it has a passive film to protect the iron rust interface. Also, many believed that there is the presence of phosphorus in the metal, and thus, it has adapted according to the existing atmospheric conditions of Delhi.

Upon iron oxidation, Goethite and Lepidocrocite are first amorphous oxy-hydroxides appears. Rust rates are high initially, and then chemical reactions take place. With this second phase, particle formation takes place. With this slow passivation of iron takes place, which reduces its rusting.

The second phase particles start acting as a cathode, while metal itself acts as the anode, which would lead to mini galvanic corrosion. There is the formation of a passive protective film on a metal that does not let it rust and corrode. Hence according to scientific analysis, this is a reason why Iron Pillar is famous for being rust-free.
