Hafnium is a heavy, steelgray metal in the reactive metals group that is very closely related to zirconium, and forms a continuous solidsolution at all concentrations of zirconium and hafnium. Hafnium occurs naturally with zirconium at a ratio of approximately 1:50, and is produced exclusively as a coproduct of nucleargrade zirconium.
