Separated in 1885 by Baron Auer von Weisbach. Neodymium is one of the more reactive members of the lanthanide group. It oxidises rapidly in air to form an oxide which rapidly spalls away to reveal fresh metal. The metal reacts slowly with cold water and rapidly with hot water. The metal is found in monazite (CePO4, a principal source of the rare earths and thorium) and orthite. It has an abundance of 38 ppm in the earth's crust. The applications for pure neodymium are limited, but it is used in alloys used to produce permanent magnets and flints. It is also used as an additive to glasses which are used in solid state lasers and light amplifiers.

Neodymium metal -  high precision density-standard cube 10x10x10mm, 7 grams in Ampoule under Argon - NEW!

Without argon this cube would turn black within a few minutes.

The cube comes without engraving but the ampoule is labelled.

Using finest materials, each density cube was lapped to 10x10x10mm by a mechanical engineering company with an accuracy of 0.01 millimeter. Each one separately ground and polished it represents the theoretical density of the respective element by its weight. The weight is not affected by the laser inscription. Information such as element symbol, name and density is durable burned at the surface. Each element even shows its specific characteristis in colour and reaction with the laser. Altogether 25 elements are planned in a complete set in a wooden case.
