Essay on iron piller
Answers
Answer:
The Iron Pillar located in Delhi, India, is a 7 m (23 ft) column in the Qutub complex, notable for the rust-resistant composition of the metals used in its construction. The pillar has attracted the attention of archaeologists andmetallurgists and has been called "a testament to the skill of ancient Indian blacksmiths" because of its high resistance tocorrosion.[1] The corrosion resistance results from an even layer of crystalline iron hydrogen phosphate forming on the highphosphorus content iron, which serves to protect it from the effects of the local Delhi climate.[2] The name of the city of Delhi is thought to be based on a legend associated with the pillar (see History of Delhi). -------------------------------------------------
