Summary
[edit]
| Description |
English: The Iron Pillar located in Delhi, India, is a 7 m (23 ft) column in the Qutab complex, notable for the rust-resistant composition of the metals used in its construction.
The pillar has attracted the attention of archaeologists and materials scientists because of its high resistance to corrosion, and has been called a "testimony to the high level of skill achieved by the ancient Indian iron smiths in the extraction and processing of iron." The corrosion resistance results from an even layer of crystalline iron hydrogen phosphate hydrate forming on the high phosphorus content iron, which serves to protect it from the effects of the local Delhi climate. The pillar weighs over 6,000 kg (13,000 lb), and is thought to have originally been erected in what is now Udayagiri by one of the Gupta monarchs in approximately 402 CE, though the precise date and location are a matter of dispute. |
