a.
Pertaining to, or containing, columbium or niobium; niobic.
n.
A brownish black mineral with a metallic luster, found in Norway. It contains niobium, titanium, yttrium, and uranium, with some other metals.
n.
A rare element of the vanadium group, first found in a variety of the mineral columbite occurring in Connecticut, probably at Haddam. Atomic weight 94.2. Symbol Cb or Nb. Now more commonly called niobium.
n.
A rare mineral, containing chiefly niobium, titanium, thorium, and cerium. It was so called by Berzelius on account of the inability of chemical science, at the time of its discovery, to separate some of its constituents.
