Strontium ist ein leichtes metallisches chemisches Element, das zur Familie der Erdalkalien gehört. Sein Symbol ist Sr und seine Ordnungszahl ist 38. Es ist eines der drei Elemente der Strontiumgruppe, das zweite ist barium und das dritte ist Calcium.
strontium ist ein weiches und duktiles Metall. Es hat eine zarte metallisch weiße Farbe und ist sehr reaktionsschnell. Seine Reaktivität kommt der von Calcium nahe, dem es in seinen chemischen Eigenschaften sehr ähnlich ist. Es ist in Salzsäure löslich und löst sich schwer in basischer Lösung. Es reagiert stark mit Wasser und setzt brennbare Gase frei.
strontium wird hauptsächlich chemisch in Metalllegierungen zum Beschichten, Schweißen, Gießen und Gießen von Metallen verwendet. Es wird auch in Sprengstoffen, Lumineszenzmitteln und Pigmenten verwendet. Strontiumhaltige Legierungen werden als Schmiermittel und für verschiedene mechanische Anwendungen verwendet.
strontium ist auch ein wichtiges Element in der Nuklearindustrie. Es wird zur Herstellung von Strontium-90-Verbindungen verwendet, einem radioaktiven Isotop zur Behandlung von Tumoren. Es ist auch eine wichtige Neutronenquelle beim Betrieb von Kernreaktoren.
In der Medizin hat strontium potenzielle Vorteile und Risiken. Studien deuten darauf hin, dass es helfen kann, die Knochen zu stärken und die Knochendichte zu verbessern. Es gibt jedoch nur begrenzte Beweise dafür, dass es das Krebsrisiko erhöhen kann, und die Gesundheitsbehörden überwachen seinen Konsum genau.
