Discovered by P.E. Lecoq de Boisbaudran in 1886 in Paris, France. Dysprosium is a silvery metal of the lanthanide group. It is relatively stable in air, reacts violently with water and dissolves in acids. Applications for this element are limited, but it is used as an alloying element to produce an alloy used for magnets, and as a poison in nuclear reactors where it stops the reaction from getting out of hand. The abundance in the Earth's crust of dysprosium is 6 ppm.

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!
