CALCIUM CARBONATE | 1317-65-3

CALCIUM CARBONATE has generally low chemical reactivity. Is non-combustible. Decomposes at high temperature (825°C) to give gaseous carbon dioxide and calcium oxide (quicklime). Incompatible with acids, alum, ammonium salts, fluorine, magnesium. Reacts with acids and acidic salts to generate gaseous carbon dioxide with effervescence (bubbling).

In its pure form, calcium carbonate is a white powder with a specific gravity of 2.71 in the calcite form or 2.93 in the aragonite form. When heated, it decomposes into calcium oxide (CaO) and carbon dioxide gas (CO 2). It also reacts vigorously with acids to release a froth of carbon dioxide bubbles.

Practically insoluble in water. Occurs extensive in rocks world-wide. Ground calcium carbonate (CAS: 1317-65-3) results directly from the mining of limestone. The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ground product either in dry or slurry form.

Formula and structure: The chemical formula of calcium carbonate is CaCO 3 and its molar mass is 100.1 g/mol. It is a salt made of the bivalent calcium cation (Ca 2+ ) and the bidentate carbonate anion (CO 3 2- ), in which the carbon is attached to two oxygen atoms through single bonds and one oxygen atom through a double bond.

CaCO3 Properties|Calcium carbonate Museum|CALFINE

Calcium carbonate (CaCO 3) is composed of carbonate ion (CO 3 ion) and calcium ion (Ca ion). Usually calcium carbonate is a white rock (or powder), but if you enlarge CaCO 3 to the numerator level, you could see a figure like right picture. Besides you'd better know that mined limeston is not a calcium carbonate but contained a little impurities.
