CAS 7440-70-2
:Calcio
Descrizione:
Calcio, con il simbolo chimico Ca e il numero CAS 7440-70-2, è un metallo alcalino-terroso essenziale per vari processi biologici e industriali. È un metallo morbido di colore bianco argenteo, relativamente reattivo, in particolare con acqua e acidi, formando idrossido di Calcio e gas idrogeno. Nella sua forma elementare, Calcio si trova tipicamente in natura come parte di composti, come il carbonato di Calcio nella pietra calcarea e il solfato di Calcio nel gesso. Ha un punto di fusione di circa 842 gradi Fahrenheit (450 gradi Celsius) e un punto di ebollizione di circa 1.470 gradi Fahrenheit (800 gradi Celsius). Calcio gioca un ruolo cruciale nei sistemi biologici, in particolare nella formazione di ossa e denti, così come nella contrazione muscolare e nella funzione nervosa. Nelle applicazioni industriali, viene utilizzato nella metallurgia, come agente riducente nell'estrazione di altri metalli e nella produzione di cemento e calce. A causa della sua reattività, Calcio deve essere conservato sotto olio o in un'atmosfera inerte per prevenire l'ossidazione.

CAS:Prodotto controllato<p>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</p>Formula:CaPurezza:Min. 95%Colore e forma:Metal Or Metallic SolidPeso molecolare:40.08 g/molRef: 3D-FC34853
