Hafnium is a chemical element; it has symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals. Its existence was predicted by Dmitri Mendeleev in 1869, though it was not identified until 1922, by Dirk Coster and George de Hevesy.

2023年12月28日 · Hafnium (pronounced as HAF-nee-uhm) belongs to the family of transition metals, denoted by the chemical symbol Hf. It has thirty-two isotopes with known half-lives, of which only six exist naturally [1, 2]. It is extracted from zircon ores whose major sources are heavy mineral sand ore deposits found in the USA, Malawi, Australia, and Brazil.
