Zirconium is a chemical element with symbol Zr and atomic number 40. The name of zirconium is taken from the name of the mineral zircon, the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that resembles hafnium and, to a lesser extent, titanium. Zirconium is mainly used as a refractory and opacifier, although it is used in small amounts as an alloying agent for its strong resistance to corrosion. Zirconium forms a variety of inorganic and organometallic compounds such as zirconium dioxide and zirconocene dichloride, respectively. Five isotopes occur naturally, three of which are stable. Zirconium compounds have no known biological role.

1) Because of zirconium's excellent resistance to corrosion, it is often used as an alloying agent in materials that are exposed to corrosive agents, such as surgical appliances, explosive primers, vacuum tube getters and filaments.
2) 90% of all zirconium produced is used in nuclear reactors because of its low neutron-capture cross-section and resistance to corrosion. Zirconium alloys are used in space vehicle parts for their resistance to heat, an important quality given the extreme heat associated with atmospheric reentry.
3) Zirconium is also a component in some abrasives, such as grinding wheels and sandpaper.
4) Zirconium is used in weapons such as the BLU-97/B Combined Effects Bomb for incendiary effect.
5) Zirconium in the oxidized form is also used in dentistry for crowning of the teeth because of its biocompatibility, strength and appearance.
6) High temperature parts such as combustors, blades and vanes in modern jet engines and stationary gas turbines are to an ever increasing extent being protected by thin ceramic layers which reduce the metal temperatures below and keep them from undergoing (too) extensive deformation which could possibly result in early failure. They are absolutely necessary for the most modern gas turbines which are driven to ever higher firing temperatures to produce more electricity at less CO2. These ceramic layers are usually composed by a mixture of zirconium and yttrium oxide.

    Bonjour, J'ai essayé de vous joindre au sujet de votre site Je constate que vous avez fais des effort pour son référencement, et vous en félscite. Néanmoins, il vous restes beaucoup beaucoup à faire pour le positioner correctement dans les results de google. il fuadrait égalemment soignier le design du site qui me parait largemment amméliorable. Si vous voulez amméliorer tout ça, je vous propose un entretien par tel pour qu'e l'on en discute, quand pensez vous ? Merci et à très bientôt André
