Discoverer: Paul-Émile Lecoq de Boisbaudran
Place: Paris, France
Year: 1886

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.

3 large beads of neodymium-, praseodymium- and Erbium glass - NEW!

Diameter ~ 20 - 22mm - weight ~ 4.3 - 5g

Doping conc.:  5 mol% Er2O3, Pr2O3, Nd2O3

Material: BaP

Nice glass beads made of optical barium phosphate glass. Doped with praseodmyium- , neodymium and erbium oxide (5 mol% concentration each). Each one hand crafted. Since this kind of glass is produced very rarely and only in charges of several hundred kgs, it is a true opportunity to get it.
