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)

How hard is hafnium?
The density of hafnium is 13,31 g/cm3.
Melting point above 3000K?
Metals: tantalum, rhenium, wolfram, osmium Nonmetals: diamond, graphite Compounds: hafnium carbide, hafnium boride, hafnium nitride, tantalum hafnium carbide, etc.
What does hafnium react with?
If there is a reaction, it it would produce hydrogen gas and a corresponding hafnium salt. For example if you use hydrochloric acid, you would get hafnium chloride.
Is hafnium flammable?
Not known but very probable not flammable.
Is hafnium a good heat conductor?
The thermal conductivity of hafnium is 23 W/m.K at room temperature.
What are the uses of hafnium?
- 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
What is the color of hafnium?
Hafnium is a metal, steel grey.
Is hafnium malleable?
Hafnium is malleable.
How hard is hafnium?
The density of hafnium is 13,31 g/cm3.
What is the origin of hafnium?
Hafnium is a natural chemical element; hafnium hasn't minerals but it is associated with zirconium (unrefined zirconium contain approx. 2 % hafnium).
Is hafnium combined or uncombined?
Pure hafnium doesn't exist in the nature; hafnium form many compounds.
Can you burn hafnium?
Fine powders of hafnium are pyrophoric.
How many isotopes does hafnium have?
There are 37 isotopes of Hafnium.
Is hafnium metal or non-metal?
Hafnium is a metal.
How is Hafnium made today?
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.
What is the appearance of hafnium?
Hafnium is a metal, steel grey appearance.
Hafnium is magnetic or non-magnetic?
Hafnium is a single element and therefore nonpolar.
