Zirconium is a lustrous, greyish-white, soft, ductile, malleable metal that is solid at room temperature, though it is hard and brittle at lesser purities. [12] In powder form, zirconium is highly flammable, but the solid form is much less prone to ignition. Zirconium is highly resistant to corrosion by alkalis, acids, salt water and other ...
Zircon (/ ˈ z ɜːr k ɒ n,-k ən /) [7] [8] [9] is a mineral belonging to the group of nesosilicates and is a source of the metal zirconium. Its chemical name is zirconium(IV) silicate, and its corresponding chemical formula is Zr SiO 4. An empirical formula showing some of the range of substitution in zircon is (Zr 1–y, REE y)(SiO 4) 1–x ...
Corrosion resistance of zirconium alloys is enhanced by intentional development of thicker passivation layer of black lustrous zirconium oxide. Nitride coatings might also be used. Whereas there is no consensus on whether zirconium and zirconium alloy have the same oxidation rate, Zircaloys 2 and 4 do behave very similarly in this respect.
Zirconium dioxide (ZrO 2 ), sometimes known as zirconia (not to be confused with zirconium silicate or zircon ), is a white crystalline oxide of zirconium . Its most naturally occurring form, with a monoclinic crystalline structure , is the mineral baddeleyite .

Organozirconium chemistry is the science of exploring the properties, structure, and reactivity of organozirconium compounds, which are organometallic compounds containing chemical bonds between carbon and zirconium. [2] Organozirconium compounds have been widely studied, in part because they are useful catalysts in Ziegler-Natta polymerization.
Naturally occurring zirconium (40 Zr) is composed of four stable isotopes (of which one may in the future be found radioactive), and one very long-lived radioisotope (96 Zr), a primordial nuclide that decays via double beta decay with an observed half-life of 2.0×10 19 years; [4] it can also undergo single beta decay, which is not yet observed, but the theoretically predicted value of t 1/2 ...
