tantalum


tantalum
n 1: a hard grey lustrous metallic element that is highly
resistant to corrosion; occurs in niobite and fergusonite
and tantalite [synonym: {tantalum}, {Ta}, {atomic number 73}]

Tantalum \Tan"ta*lum\, n. [NL. So named on account of the
perplexity and difficulty encounterd by its discoverer
(Ekeberg) in isolating it. See {Tantalus}.] (Chem.)
A rare nonmetallic element found in certain minerals, as
tantalite, samarskite, and fergusonite, and isolated as a
dark powder which becomes steel-gray by burnishing. Symbol
Ta. Atomic weight 182.0. Formerly called also {tantalium}.
[1913 Webster]
