zir·co·ni·um

 (zûr-kō′nē-əm)
n. Symbol Zr
A lustrous, grayish-white, strong, ductile metallic element obtained primarily from zircon and used in nuclear reactors because of its high resistance to corrosion, used in ceramic and refractory compounds, and alloyed with niobium, zinc, and other metals. Atomic number 40; atomic weight 91.22; melting point 1,855°C; boiling point 4,409°C; specific gravity 6.52 (at 20°C); valence 2, 3, 4. See Periodic Table.

zirconium

(zɜːˈkəʊnɪəm)
n
(Elements & Compounds) a greyish-white metallic element, occurring chiefly in zircon, that is exceptionally corrosion-resistant and has low neutron absorption. It is used as a coating in nuclear and chemical plants, as a deoxidizer in steel, and alloyed with niobium in superconductive magnets. Symbol: Zr; atomic no: 40; atomic wt: 91.224; valency: 2, 3, or 4; relative density: 6.506; melting pt: 1855±2°C; boiling pt: 4409°C
[C19: from New Latin; see zircon]
zirconic adj

zir•co•ni•um

(zɜrˈkoʊ ni əm)

n.
a metallic element resembling titanium chemically: used in steel metallurgy, as a scavenger and refractory, and to make vitreous enamels opaque. Symbol: Zr; at. wt.: 91.22; at. no.: 40; sp. gr.: 6.49 at 20°C.
[1800–10; < New Latin; see zircon]

zir·co·ni·um

(zûr-kō′nē-əm)
Symbol Zr A shiny, grayish-white metallic element that occurs primarily in zircon. It is used to build nuclear reactors because it is not damaged from bombardment by neutrons and remains strong at high temperatures. Zirconium is also highly resistant to corrosion, making it a useful component of pumps, valves, and alloys. Atomic number 40. See Periodic Table.
