Zirconium

About Zirconium Metal (Zr) and Zirconium Alloys

Zirconium (Zr) is a highly corrosion resistant metal that is us used for many products for specialized chemical environments (primarily acetic and hydrochloric acids). Some include pumps, vaolo, tono karihi, tukatuka matū, waka reactor, kaiwhakawhiti wera me te maha atu. The nuclear power industry uses nearly 90% o te zirconium i hangaia i ia tau. 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 form vacuum tubes. Zirconium metal is weldable and formable.

Zirconium 702 offers excellent corrosion protection with resistance to stress-corrosion cracking and crevice corrosion. It’s often used for chemical processing. Alloyed with 2 ki 3 percent Columbium, zirconium 705 is significantly stronger and more ductile than zirconium 702 with almost equal corrosion resistance, making it the alloy of choice for most zirconium fasteners. In addition to resisting HCl at all concentrations and at temperatures above the boiling temperature, zirconium and its alloys also have excellent resistance in sulfuric acid at temperatures above boiling and concentrations to 70%. Corrosion rate in nitric acid is less than 1 mil/year at temperatures above boiling and concentrations to 90%. The metals also resist most organics such as acetic acid and acetic anhydride as well as citric, lactic, tartaric, oxalic, tannic, and chlorinated organic acids. He iti nei nga konganuku haunga te zirconium ka taea te whakamahi i nga waahanga matū e hiahia ana kia whakapiri atu ki nga waikawa kaha me nga kawakore. Heoi, Kaore he aukati a te zirconium i te waikawa hydrofluoriki a he tere te whakaekehia, ahakoa i nga kukū iti rawa. Kei kona 4 momo o te waikura aukati i te zirconium whakauru i te umanga matū: Zr702, Zr704, Zr705 me te Zr706, te tono ki nga momo rauemi me nga tikanga matū. Ko enei awangawanga e wha o te koranu zirconium ka rite te ahua, engari he tino rereke o raatau miihini. Ko te kaha kaha o te Zr705 ko te rua o te Zr702. I te nuinga o te wa ka whakamahia te Zr705 ki nga taputapu matū he nui ake nga whakaritenga mo te kaha. Engari i te waikawa sulfuric kei roto te FeCl3, Ko nga Zr702 me te Zr704 nga waikura aukati he pai ake i te Zr705 me te Zr706. He nui te kaha o te Zr706 me te roa o tona kaha, ka whakamahia hoki ki te mahi wera wera.

Zirconium is also highly resistant to heat and corrosion, and it also forms many useful compounds and alloys. These strengths make it an ideal component for nuclear reactions, and it is also used in laboratory equipment, metallurgy and surgical appliances. Jet engines and gas turbines may also use zirconium and zirconium alloys to prevent metals from warping due to high heat exposure. Zirconium (tohu ngota: Zr, tau ngota: 40) he Poraka D, Rōpū 4, Wā 5 huānga me te taumaha ngota o 91.224. Zirconium Bohr ModelThe number of electrons in each of Zirconium’s shells is 2, 8, 18, 10, 2 and its electron configuration is [Kr] 4d2 5s2. The zirconium atom has a radius of 160 pm and a Van der Waals radius of 186 pm. Zirconium was discovered by Martin Heinrich Klaproth in 1789 and first isolated by Jöns Jakob Berzelius in 1824. In its elemental form, zirconium has a silvery white appearance that is similar to titanium.

Zirconium’s principal mineral is zircon (zirconium silicate). Elemental Zirconium is commercially produced as a byproduct of titanium and tin mining and has many applications as a opacifier and a refractory material. It is not found in nature as a free element. The name of zirconium comes from the mineral zircon, the most important source of zirconium, and from the Persian wordzargun, meaning gold-like.
