Zirconium is a lustrous transition metal in group 4, chemically close to hafnium and titanium. It occurs mainly in zircon and related heavy minerals, almost always with hafnium as a companion. The metal is valued for its very low thermal-neutron absorption and its stable, adherent oxide film, which give it a central role in nuclear reactor materials and in corrosion-resistant alloys.
Reactor-grade zirconium is essentially free of hafnium. Zircaloy(R) is an important alloy developed specifically for nuclear applications. Zirconium is exceptionally resistant to corrosion by many common acids and alkalis, by sea water, and by other agents. Alloyed with zinc, zirconium becomes magnetic at temperatures below 35°K.
The name derives from the Arabic zargun for "gold-like". It was discovered in zirconia by the German chemist Martin-Heinrich Klaproth in 1789. Zirconium was first isolated by Swedish chemist Jöns Jacob Berzelius in 1824 in an impure state, and finally by the chemists D. Lely, Jr. and L. Hamburger in a pure state in 1914.
Zirconium was discovered by Martin Heinrich Klaproth, a German chemist, while analyzing the composition of the mineral jargon (ZrSiO4) in 1789. Zirconium was isolated by Jöns Jacob Berzelius, a Swedish chemist, in 1824 and finally prepared in a pure form in 1914. Obtaining pure zirconium is very difficult because it is chemically similar to hafnium, an element which is always found mixed with deposits of zirconium. Today, most zirconium is obtained from the minerals zircon (ZrSiO4) and baddeleyite (ZrO2) through a process known as the Kroll Process.
From the Persian zargun, gold like. Zircon, the primary gemstone of zirconium, is also known as jargon, hyacinth, jacinth, or ligure. This mineral, or its variations, is mentioned in biblical writings. The mineral was not known to contain a new element until Klaproth, in 1789, analyzed a jargon from Ceylon and identified the new element, which Werner named zircon (silex circonius), and which Klaproth called Zirkonertz (zirconia). The impure metal was first isolated by Berzelius in 1824 by heating a mixture of potassium and potassium zirconium fluoride in a small decomposition process they developed.
Pure zirconium is a silvery-gray, ductile metal when clean and massive. Finely divided zirconium can appear dark and is much more reactive than bulk metal. At ordinary temperatures the surface is protected by a thin layer of zirconium dioxide, ZrO₂.
The dominant high-value use of zirconium metal is in cladding and structural components for water-cooled nuclear fuel, where hafnium must be removed because it absorbs neutrons strongly. Zirconium alloys are also used in chemical-processing equipment exposed to corrosive media. Zirconium dioxide, ZrO₂, is used in refractories, ceramics, oxygen sensors, thermal-barrier coatings, and dental ceramics. Zirconium compounds serve in pigments, catalysts, tanning, and specialty glass formulations.
Zirconium is a corrosion resistant metal that is used in high performance pumps and valves. Since it also does not easily absorb neutrons, zirconium is widely used in nuclear reactors. The nuclear power industry uses nearly 90% of the zirconium produced each year, which must be nearly free of hafnium. Zirconium is also used as an alloying agent in steel, to make some types of surgical equipment and as a getter, a material that combines with and removes trace gases from vacuum tubes.
Zircon (ZrSiO4) is a zirconium compound that can take many different forms, the most popular of which is a clear, transparent gemstone that can be cut to look like diamond and is frequently used in jewelry. Zirconium dioxide (ZrO2) can withstand very high temperatures and is used to make crucibles and to line the walls of high temperature furnaces. Zirconium carbonate (3ZrO2·CO2·H2O) is used in lotions to treat poison ivy.
It is used extensively by the chemical industry where corrosive agents are employed. Zirconium is used as a getter in vacuum tubes, as an alloying agent in steel, in surgical appliances, photoflash bulbs, explosive primers, rayon spinnerets, lamp filaments, etc. It is used in poison ivy lotions in the form of the carbonate as it combines with urushiol. With niobium, zirconium is superconductive at low temperatures and is used to make superconductive magnets, which offer hope of direct large-scale generation of electric power. Zirconium oxide (zircon) has a high index of refraction and is used as a gem material. The impure oxide, zirconia, is used for laboratory crucibles that will withstand heat shock, for linings of metallurgical furnaces, and by the glass and ceramic industries as a refractory material. Its use as a refractory material accounts for a large share of all zirconium consumed.
Isotopes in Industry
Zirconium enriched in 90Zr has been proposed for the cladding (covering) of reactor fuel elements (Fig. IUPAC.40.1) because it has a lower neutron absorption cross section than natural abundances of zirconium and is well suited for coverage of metal parts without absorbing neutrons [307] M. D. DeHart, H. Zhang, E. Shaber, M. A. Jessee. “A study of fast reactor fuel transmutation in a candidate dispersion fuel design”, in 11th Information Exchange Meeting on Actinide and Fission Product Partitioning and Transmutation..
Zirconium chemistry is dominated by the +4 oxidation state, reflecting the stability of Zr⁴⁺ in oxides and salts. Zirconium dioxide, ZrO₂, is a refractory ceramic with monoclinic, tetragonal, and cubic forms; stabilized zirconias contain added oxides to retain high-temperature structures. Zirconium tetrachloride, ZrCl₄, is an important volatile precursor for metal production and organozirconium chemistry. Zircon, ZrSiO₄, is the principal mineral source. Lower oxidation states are known but are less common and often require special conditions.
See more information at the Zirconium compound page.
Massive zirconium metal has low acute toxicity and is usually limited in hazard by dust generation and processing conditions. Finely divided powder, turnings, and some dry residues are combustible and can ignite in air. Zirconium compounds vary in irritation and corrosivity; zirconium tetrachloride, ZrCl₄, reacts with moisture to release hydrogen chloride, HCl. Nuclear-grade zirconium is not inherently radioactive, but service in reactors can activate or contaminate materials.
Zirconium is a lithophile element and is held mainly in resistant minerals, especially zircon, rather than in soluble aqueous forms. Its compounds are generally not very mobile under ordinary surface conditions because zirconium(IV) hydrolyzes strongly and forms insoluble oxides and hydroxides. Weathering releases zircon grains to sediments and heavy-mineral sands, where they can persist for very long periods.
Commercial zirconium starts with mining of zircon-bearing heavy-mineral sands, often associated with titanium minerals such as ilmenite and rutile. For nuclear applications, zirconium must be separated from chemically similar hafnium, an expensive step that creates distinct nuclear-grade and hafnium-bearing markets. Metal is commonly produced through conversion to zirconium tetrachloride, ZrCl₄, followed by reduction. Demand is driven by nuclear fuel fabrication, ceramics, foundry sands, refractories, and specialty chemicals. Recycling is important for clean metal scrap, while ceramic and mineral uses are less readily recovered.
Zirconium is produced from the mineral zircon (ZrSiO4). It is found in abundance in S-type stars, and has been identified in the sun and meteorites. Analysis of lunar rock samples obtained during the various Apollo missions to the moon show a surprisingly high zirconium oxide content, compared with terrestrial rocks.
Zirconium is produced mainly by neutron-capture processes in evolved stars and by related heavy-element nucleosynthesis before incorporation into later generations of planets and meteorites. It is not among the most abundant cosmic elements, but it is readily detected in stellar spectra. In planetary materials it behaves as a refractory lithophile element and concentrates in silicate minerals rather than metallic cores.
- Zirconium and hafnium are so chemically similar that their separation became a major technical problem for reactor use.
- Ancient zircon grains preserve some of the oldest known records of Earth's crust.
- Zirconium dioxide can be made tough for ceramics by stabilizing high-temperature crystal forms.
- Bulk zirconium resists many acids, but hydrofluoric acid attacks its protective oxide film.
- The name zirconium comes from zircon, not from the modern synthetic gemstone cubic zirconia.

Naturally occurring zirconium contains five isotopes. Fifteen other isotopes are known to exist. Zircon, ZrSiO4, the principal ore, is pure ZrO2 in crystalline form having a hafnium content of about 1%. Zirconium also occurs in some 30 other recognized mineral species. Zirconium is produced commercially by reduction of chloride with magnesium (the Kroll Process), and by other methods. It is a grayish-white lustrous metal. When finely divided, the metal may ignite spontaneously in air, especially at elevated temperatures. The solid metal is much more difficult to ignite. The inherent toxicity of zirconium compounds is low. Hafnium is invariably found in zirconium ores, and the separation is difficult.

Sources of this element.
Zirconium is produced from the mineral zircon (ZrSiO4). It is found in abundance in S-type stars, and has been identified in the sun and meteorites. Analysis of lunar rock samples obtained during the various Apollo missions to the moon show a surprisingly high zirconium oxide content, compared with terrestrial rocks.
