La
Lanthanum


Atomic no.:
57
Atom. weight: 138.9055
Density: 6.162
Class:
Rare earth metal
Melting point: 920°C
Boiling point: 3469°C
Colour: silvery
   
Discoverer: Carl Gustav Mosander
Place: Stockholm, Sweden
Year: 1839

Discovered in 1839 by C.G. Mosander in Stockholm, Sweden. Lanthanum is a soft, ductile, white metal which oxidises rapidly in air. It is one of the most reactive of the lanthanide group of elements, reacting with water to produce hydrogen gas. It has an abundance in the earth's crust of 32 ppm. At very low temperatures, lanthanum is super conducting (at 6K). It is used to manufacture special grades of optical glass which have specific refractive properties. Lanthanum can also be used in flints, and La3+ is used as a biological tracer for Ca2+. Radioactive isotopes of lanthanum have been tested for the treatment of cancer.

Lanthanum metal -  high precision density-standard cube 10x10x10mm, 6.12 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.
