Description
Pure Hafnium Metal (Hf) and Hafnium Alloys
Overview
Hafnium (Hf) is a shiny, silvery metal known for its excellent corrosion resistance and high strength. Similar to zirconium, hafnium forms a tough, protective oxide layer that prevents corrosion, making it highly durable. It is resistant to most acids and bases except hydrofluoric acid. Due to its similar atomic size to zirconium, separating hafnium from zirconium is challenging.

History
Hafnium was predicted by Dmitri Mendeleev in 1869 but was first isolated by Dirk Coster and George de Hevesy in 1922. It does not occur naturally as a free element but is found in zirconium compounds like zircon.
