CAS 7440-70-2
:Calcium
Description:
Calcium, with the chemical symbol Ca and CAS number 7440-70-2, is an alkaline earth metal that is essential for various biological and industrial processes. It is a soft, silvery-white metal that is relatively reactive, particularly with water and acids, forming calcium hydroxide and hydrogen gas. In its elemental form, calcium is typically found in nature as part of compounds, such as calcium carbonate in limestone and calcium sulfate in gypsum. It has a melting point of about 842 degrees Fahrenheit (450 degrees Celsius) and a boiling point of approximately 1,470 degrees Fahrenheit (800 degrees Celsius). Calcium plays a crucial role in biological systems, particularly in the formation of bones and teeth, as well as in muscle contraction and nerve function. In industrial applications, it is used in metallurgy, as a reducing agent in the extraction of other metals, and in the production of cement and lime. Due to its reactivity, calcium must be stored under oil or in an inert atmosphere to prevent oxidation.

CAS:Controlled Product<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:CaPurity:Min. 95%Color and Shape:Metal Or Metallic SolidMolecular weight:40.08 g/molCalcium Metal Granular extrapure, 98%, 10-20 mesh
