Discovery and Application of Hafnium Elements with High Melting Points
Hafnium Metal is First Extracted D. Koster and Hervez, a Swedish chemist and physicist from the Netherlands, found hafnium among zircons in Greenland and Norway. The element was named Hafnium by the Latin name of Copenhagen. Hervis and Koster, in 1925, separated titanium and zirconium using the method of crystallization containing fluorosalts. They then reduced…
