Hafnium is separated from zirconium minerals.
Hafnium is malleable.
Hafnium is a shiny, silvery metal that does not have a distinct color.
Hafnium is used in nuclear reactors as a control rod material to regulate the nuclear fission process. It has a high neutron-capture cross-section, meaning it is effective in absorbing neutrons and controlling the rate of the nuclear reaction. The addition of hafnium control rods helps maintain the reactor at a safe and stable operating condition.
Pure hafnium doesn't exist in the nature; hafnium form many compounds.
Fine powders of hafnium are pyrophoric.
There are 37 isotopes of Hafnium.
Hafnium-174 is the most common isotope of hafnium, making up about 31% of naturally occurring hafnium.
Hafnium is found in tandem with zirconium deposits. It is separated from the zirconium during refinement as hafnium chloride. It is then reduced with magnesium to produce pure hafnium.
Hafnium is a metal, steel grey appearance.
Hafnium is a single element and therefore nonpolar.
Yes, hafnium is reactive, but not like sodium or potassium.
The density of hafnium is 13,31 g/cm3.
