WAS BEDEUTET BERYLLIUM AUF ENGLISCH
Beryllium
Beryllium ist das chemische Element mit dem Symbol Be und der Ordnungszahl 4. Da jedes in den Sternen synthetisierte Beryllium kurzlebig ist, ist es ein relativ seltenes Element im Universum. Es ist ein zweiwertiges Element, das natürlich nur in Kombination mit anderen Elementen in Mineralien auftritt. Bemerkenswerte Edelsteine, die Beryllium enthalten, schließen Beryl und Chrysoberyl ein. Als freies Element ist es ein stahlgraues, starkes, leichtes und sprödes Erdalkalimetall. Beryllium verbessert viele physikalische Eigenschaften, wenn es als Legierungselement zu Aluminium, Kupfer, Eisen und Nickel hinzugefügt wird. Werkzeuge aus Beryllium-Kupferlegierungen sind stark und hart und erzeugen keine Funken, wenn sie auf eine Stahloberfläche schlagen. Bei strukturellen Anwendungen macht die Kombination von hoher Biegesteifigkeit, thermischer Stabilität, Wärmeleitfähigkeit und geringer Dichte Berylliummetall zu einem wünschenswerten Luft- und Raumfahrtmaterial für Flugzeugkomponenten, Raketen, Raumfahrzeuge und Satelliten. Wegen seiner geringen Dichte und Atommasse ist Beryllium für Röntgenstrahlen und andere Formen ionisierender Strahlung relativ transparent; Daher ist es das häufigste fenstermaterial für röntgengeräte und komponenten von partikelphysikversuchen.
