Is zirconium Reactive or nonreactive?
Due to its non-reactive nature, zirconium may be used in alloys for pipes and fittings in corrosive environments.
Is zirconium a radioactive element?
Zr, the heaviest isotope of zirconium, is the most radioactive, with an estimated half-life of 30 milliseconds. Radioactive isotopes at or above mass number 93 decay by electron emission, whereas those at or below 89 decay by positron emission.
What is pure zirconium?
Zirconium is a silver-gray transition metal, a type of element that is malleable and ductile and easily forms stable compounds. It is also highly resistant to corrosion. Zirconium and its alloys have been used for centuries in a wide variety of ways. It is commonly used in corrosive environments.

How many neutrons does zirconium have?
Typical zirconium contains about 50 neutrons, but ⁸⁸Zr, which is radioactive and not found naturally on Earth, has fewer than normal, with 48 neutrons.
Is zirconium a corrosion?
Zirconium exhibits superb corrosion resistance in most organic and inorganic acids, salt solutions, strong alkalis and a few molten salts. The passive oxide film (corrosion barrier) is stable in both reducing and oxidizing conditions. Zirconium is excellent in both acidic and basic solutions.
Is zirconium toxic to humans?
Toxicity Most zirconium compounds have low systemic toxicity due to their poor solubility. However, some soluble compounds, such as zirconium tetrachloride, are irritants and may cause corrosive injury. In addition, skin and lung granulomas have been reported following repeated zirconium exposure.
What is black zirconium?
Black Zirconium is a type of metal that has been exposed to high heat to create its unique appearance. Zirconium in its pure form is a light gray color, but it can be oxidized in order to make it black and more stylish.
What are the hazards of the element zirconium?
Zirconium: health and environmental effects. Health effects of zirconium. Zirconium and its salts generally have low systemic toxicity. While zirconium is not toxic, it can cause contact irritation to the skin and eyes. If exposed, people should wash their skin or flush their eyes.
How did the element zirconium get its name?
Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon; zar-gun, “gold-like” or “as gold”), the most important source of zirconium.
What group of elements does zirconium belong to?
zirconium (Zr), chemical element, metal of Group 4 (IVb) of the periodic table, used as a structural material for nuclear reactors. atomic number 40 atomic weight 91.22 melting point 1,852 °C (3,366 °F) boiling point 3,578 °C (6,472 °F) specific gravity 6.49 at 20 °C (68 °F) oxidation state +4
How much does the element zirconium cost?
Zirconium of about 99.6% purity is available at a cost of about $150/kg. Uses: The metal is used in the nuclear industry for cladding fuel elements since it has a low absorption cross section for neutrons.
