What is the price of hafnium?
Costs. The price of the metal is in the broad range between $100/lb and $500/lb, depending on purity and quantity. The yearly demand for hafnium in the U.S. now exceeds 100,000 lb.
Can hafnium be recycled?
Hafnium scrap and hafnium alloy scrap is useful as a control rod material in nuclear reactors and as a superalloy. When recycled as a superalloy, hafnium scrap and hafnium alloy scrap can act as a scavenger metal in the retrieval of oxygen and nitrogen.
Where is hafnium found in the world?
Source: Hafnium is not found free in nature but is found in most zirconium minerals at a concentration of between one and five percent. Commercially, hafnium is produced as a by-product of zirconium refining. This is done using the Kroll Process, reducing the tetrachloride with magnesium or with sodium.
Is hafnium toxic?
Hafnium metal has no known toxicity. The metal is completely insoluble in water, saline solutions or body chemicals. Exposure to hafnium can occur through inhalation, ingestion, and eye or skin contact. Overexposure to hafnium and its compounds may cause mild irritation of the eyes, skin, and mucous membranes.
What makes hafnium unique?
A shiny, silvery metal that resists corrosion and can be drawn into wires. Hafnium is a good absorber of neutrons and is used to make control rods, such as those found in nuclear submarines. It also has a very high melting point and because of this is used in plasma welding torches.
How strong is hafnium?
Hafnium is the 45th most abundant element on Earth, comprising about 3.3 parts per million (ppm) of the Earth’s crust by weight, according to Chemicool. Hafnium is quite resistant to corrosion because of the formation of an oxide film on exposed surfaces.
Is hafnium a rare earth metal?
The first rare-earth mineral discovered (1787) was gadolinite, a black mineral composed of cerium, yttrium, iron, silicon, and other elements….Rare-earth element.

What can hafnium do?
Hafnium is a good absorber of neutrons and is used to make control rods, such as those found in nuclear submarines. It also has a very high melting point and because of this is used in plasma welding torches. Hafnium has been successfully alloyed with several metals including iron, titanium and niobium.
What are the current prices of hafnium in the market?
They are primarily driven by supply, demand and energy prices. In 2019, prices of pure Hafnium were at around 1200 $/kg. The heavy mineral sands ore deposits of the titanium ores ilmenite and rutile yield most of the mined zirconium, and therefore also most of the hafnium.
Is the hafnium element similar to zirconium?
Hafnium is a lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals.
Which is the best source of hafnium for nuclear power?
Thus, a nearly complete separation of zirconium and hafnium is necessary for their use in nuclear power. The production of hafnium-free zirconium is the main source for hafnium. Source: www.luciteria.com
What is the hardness of a hafnium Crystal?
Hafnium is has a hardness of approximately 5.5. A possible crystal structure of Hafnium is hexagonal close-packed structure. In metals, and in many other solids, the atoms are arranged in regular arrays called crystals. A crystal lattice is a repeating pattern of mathematical points that extends throughout space.
