CAS 7440-70-2

Kalzium

Beschreibung:

Kalzium, mit dem chemischen Symbol Ca und der CAS-Nummer 7440-70-2, ist ein Erdalkalimetall, das für verschiedene biologische und industrielle Prozesse unerlässlich ist. Es ist ein weiches, silberweißes Metall, das relativ reaktiv ist, insbesondere mit Wasser und Säuren, und dabei Kalzium-Hydroxid und Wasserstoffgas bildet. In seiner elementaren Form wird Kalzium typischerweise in der Natur als Teil von Verbindungen gefunden, wie Kalzium-Carbonat in Kalkstein und Kalzium-Sulfat in Gips. Es hat einen Schmelzpunkt von etwa 842 Grad Fahrenheit (450 Grad Celsius) und einen Siedepunkt von etwa 1.470 Grad Fahrenheit (800 Grad Celsius). Kalzium spielt eine entscheidende Rolle in biologischen Systemen, insbesondere bei der Bildung von Knochen und Zähnen sowie bei der Muskelkontraktion und der Nervenfunktion. In industriellen Anwendungen wird es in der Metallurgie, als Reduktionsmittel bei der Gewinnung anderer Metalle und in der Zement- und Kalkproduktion verwendet. Aufgrund seiner Reaktivität muss Kalzium unter Öl oder in einer inert Atmosphäre gelagert werden, um Oxidation zu verhindern.

Calcium is a chemical element with the symbol Ca and atomic number 20. It has an atomic weight of 40.078, which means that it is 40.078 times heavier than hydrogen. Calcium is an alkaline earth metal, as are magnesium and barium. Calcium is classified as a hard metal because it has a high melting point and its oxide layer resists corrosion by water and air. The ionized form of calcium (Ca2+) may be found in the cytosol, or in transport vesicles in muscle cells or other types of cells such as those of the intestine or bone cells. The main biological role of calcium ions is to maintain the potential difference across excitable cell membranes, enabling normal nerve transmission and muscle contraction, including the contraction of heart muscles. The concentration of calcium ions in extracellular fluid is tightly regulated by the kidneys under instruction from parathyroid hormone (PTH) and calcitonin hormones to keep blood calcium levels within a narrow range
