Article · Deutsch
Strontium ist ein chemisches Element mit dem Elementsymbol Sr und der Ordnungszahl 38. Im Periodensystem steht es in der 5. Periode sowie der 2. Hauptgruppe, bzw. der 2. IUPAC-Gruppe und gehört damit zu den Erdalkalimetallen. Es ist ein weiches (Mohshärte: 1,5) und sehr reaktionsfreudiges Metall. Das Element wurde 1790 von Adair Crawford entdeckt und nach seinem ersten Fundort Strontian in Schottland benannt. Elementar, allerdings noch durch Fremdbeimengungen verunreinigt, konnte es 1808 mittels Elektrolyse durch Humphry Davy dargestellt werden. Robert Bunsen gelang 1855 auch die Darstellung reinen Strontiums. Das Element wird nur in geringen Mengen, vor allem für Kathodenstrahlröhren, Pyrotechnik (rote Flammenfarbe), Dauermagnete und in der Aluminiumverhüttung verwendet. Strontium kommt in geringen Mengen im menschlichen Körper vor, hat jedoch keine bekannte biologische Bedeutung und ist nicht essentiell. Da Strontium chemisch dem Calcium sehr ähnlich ist, wird es in Knochen „eingebaut“ und hat daher eine hohe biologische Halbwertszeit – dies ist sowohl Basis der gezielten Nutzung radioaktiver Isotope von Strontium in der Krebstherapie als auch Basis der Schädlichkeit radioaktiver Strontiumisotope für gesunde Menschen. Strontiumranelat ist ein Arzneistoff zur Behandlung der Osteoporose.
