Har nettopp fått tak i

Sakset fra manualen:
Tantalum
Tantalum is a rare metal of dark grey colour with a blue shade. It is rarely used in the watch industry as it is extremely hard to work with due to a very high fusion temperature, 3’016°, and a density of 16.65. Its boiling point is 5'458°. Tantalum is also precious as it offers a prefect resistance to corrosion and wear.
This metal has been discovered in 1801 by the British chemist Charles Hatchett. In 1802, another Swedish scientist by the name of Anders Gustaf Ekeberg discovers an oxide very hard to dissolve and work with, which he baptised “tantale”, named after the Greek God Tántalos. Tantalum is finally isolated in 1820 by Jöns Jacob Berzélius.
At the beginning of the 1900’s, Tantalum finds its first application for electric bulbs’ incandescent filaments until the discovery of tungsten. In 1940, it is used to make condensers. Two years later, the first exploitation of colombo-tantalite in Belgian Congo sees the light of day.
Tantalum is also frequently used in medicine thanks to its total biocompatibility and also utilized in aeronautics
