n. 锆

锆

zirconium
n 1: a lustrous grey 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 [synonym: {zirconium}, {Zr}, {atomic number 40}]

Zirconium \Zir*co"ni*um\, n. [NL.] (Chem.)
A rare element of the carbon-silicon group, intermediate
between the metals and nonmetals, obtained from the mineral
