Terbium was discovered in 1843 by C.G. Mosander in Stockholm and was named after the Swedish town of Ytterby. A lanthanide group metal, it is soft, malleable and ductile. Terbium has an abundance of 1.1 ppm in the earth's crust and is found in minerals in combination with other lanthanide group elements. It is slowly oxidized in air, the rate of the reaction being increased if terbium powder is used. Terbium reacts slowly with cold water. Terbium is used in the semiconductor industry as a dopant.

As professional producer and seller of chemical element samples for science and education we are able to offer you:
  • Surfaces are mechanically cleaned and oxidations removed
  • We do not fill any crumbs, filings or other low value material but ONLY carefully hand-selected pieces!
  • glass-ampoules are carefully cleaned and dried by a special process for several hours to remove even the slightest traces of humidity to make the samples last a life-long.
  • We use shatter-proof tempered glass, which are able to survive a 1 meter drop on a tiled floor.
  • Some elements like Europium, Lanthanum and Cerium are handled and filled under very dry and oxygen free atmosphere in a glove-box to keep the surface as shiny as possible.
  • lifelong warranty on breakage - should an ampoule break accidentally we replace it for free!
