Hafnium Elements Database

Hafnium (atomic number 72, symbol Hf) is a transitional metal and a chemical element, which chemically resembles zirconium. It is a silvery grey, lustrous, and ductile metal found in zirconium minerals. Hafnium is also corrosion resistant, but zirconium impurities affect its physical properties and its nuclear properties, in particular.
