🔬 Hafnium Properties
Hafnium is ductile, corrosion-resistant, and strong. It melts at 2233°C (4051°F), loves oxygen, and mimics zirconium closely.
🧪 How Was Hafnium Discovered?
In 1923, Dutch physicist Dirk Coster and Hungarian chemist George de Hevesy found Hafnium in zirconium ore via X-ray spectroscopy, naming it after Hafnia, Latin for Copenhagen.
