Terbium
Atomic no.:
65
Atom. weight: 158.92534
Density: 8.253
Class:
Rare earth metal
Melting point: 1356°C
Boiling point: 3230°C

Discoverer: Carl Gustav Mosander
Place: Stockholm, Sweden
Year: 1843

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.

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.
