The price is very dependent on purity.
A possible price in 2010 is 250 US $ per kg.
Hafnium is a metal, steel grey.
Hafnium is a natural chemical element; hafnium hasn't minerals but it is associated with zirconium (unrefined zirconium contain approx. 2 % hafnium).
Hafnium is a metal.
Hafnium is a single element and therefore nonpolar.
This element costs $120 for 100 grams. The prices of different hafnium products with different specifications can vary a lot. If you would like to find a more detailed answer, I suggest you to contact one of the major hafnium products suppliers. The one I used to deal with is Stanford Materials, they provide a wide range of hafnium products at competitive prices.
Hafnium (Hf) is a natural chemical element.
900 $
- neutron absorbent in control rods of nuclear reactors - hafnium oxide is used as electrical insulator for microprocessors - hafnium is rarely used as alloying element for very special alloys - the isomer 178m2Hf can be used as a nuclear weapon (emitter of gamma rays) by the United States
Nothing on the list below is not an example of a good conductor.
Hafnium is a metal, steel grey.
Hafnium is malleable.
Hafnium is a rare element with rare applications: - component of control rods for nuclear reactors - component of some alloys - getter in lamps and tubes - electrode for plasma cutters - hafnium dioxide was recently used as an electrical insulator in microprocessors - hafnium carbide has a very great point of melting (the most refractory compound known today) - possible use in weapons (USA)
The density of hafnium is 13,31 g/cm3.
Hafnium is a natural chemical element; hafnium hasn't minerals but it is associated with zirconium (unrefined zirconium contain approx. 2 % hafnium).
Pure hafnium doesn't exist in the nature; hafnium form many compounds.
Fine powders of hafnium are pyrophoric.
There are 37 isotopes of Hafnium.
