Terbium metal is a relatively resistant lanthanoid. Terbium metal has some special technical applications, especially in optoelectronics. Terbium(III)-ions can fluoresce very good in green and yellow, so terbium metal is used in in CRT television sets, similar to europium metal.
Amazing Terbium metal standard density cube 10x10x10mm, 99.9% pure. The sample weighs approx. 8 grams (with a tolerance of ± 0.1gram), which is the theoretical density of the Terbium metal itself. This cube is amazing for any science classrooms, schools, universities and collectors. Pure terbium metal cube for element collection.
