(Nükleer Bilimler) zirconium
a metallic chemical element (symbol Zr) with an atomic number of 40
(Zr) A strong, ductile metal obtained by the chemical processing of zircon-bearing sands It has good corrosion resistance at high temperatures and is used as a structural material in nuclear reactors and cladding material for uranium
{i} (Zr) metallic chemical element (Chemistry)
A rare element of the carbon-silicon group, intermediate between the metals and nonmetals, obtained from the mineral zircon as a dark sooty powder, or as a gray metallic crystalline substance
Metallic chemical element, one of the transition elements, chemical symbol Zr, atomic number
Zirconium is a metallic element with atomic number of 40 An alloy of zirconium known as Zircaloy is extensively used for the cladding of nuclear fuel elements
A grayish-white lustrous metal which is commonly used in an alloy form (i e zircaloy) to encase fuel rods in nuclear reactors Back to Tracking 1998 Back to Proliferation News and Resources
The metal is hard and brittle when impure, soft and ductile when highly purified. It is relatively abundant, occurring as zircon (also marketed as a natural gemstone) and baddeleyite. Highly transparent to neutrons, zirconium became important in the 1940s in nuclear energy applications such as fuel cladding. Other uses are in alloys, fireworks, and flashbulbs and as a scavenger for oxygen and other gases. Its compounds, in most of which it has valence 4, are important industrial materials. Zirconia (the oxide) is used in piezoelectric crystals (see piezoelectricity), high-frequency induction coils, coloured glazes and glasses, and heat-resistant fibres; zirconium carbonate is employed in preparations to treat the rash of poison ivy
Chemical symbol Zr A steel-gray, strong, ductile metal obtained by chemical processing of zircon-bearing sands Minor metal has good corrosion-resistance, especially at elevated temperatures Used in steel making, and as structural material in nuclear reactors and cladding material for uranium
A master alloy element found in several titanium alloys used to strengthen both alpha and beta microstructures Typical weight percentages are from 2 to 8%
Symbol Zr
Atomic weight, 90
a lustrous gray strong metallic element resembling titanium; it is used in nuclear reactors as a neutron absorber; it occurs in baddeleyite but is obtained chiefly from zircon
