Calcium carbonate(Cas 471-34-1) Usage

Description

Calcium carbonate (CaCO3) is a naturally occurring compound found in limestone, marble, and chalk. It’s produced mainly through the calcination of limestone to yield calcium oxide (CaO), which is then carbonated by adding CO2. This process can be controlled to achieve specific crystal sizes for various applications. Calcium carbonate is widely used in industries such as agriculture for soil neutralization, in pharmaceuticals as an antacid, and as a filler in products like paper and plastics. Additionally, its polymorphs, including calcite and aragonite, exhibit different properties suitable for diverse applications, from biomaterials to targeted drug delivery systems.
Industrial Applications An essential component of cement and concrete, and used as a limestone aggregate in construction. Used in the production of paper, plastics, rubber, paints, and coatings to improve texture and whiteness.
Agricultural Uses Used to neutralize soil acidity (liming) and improve soil structure.
Pharmaceutical Applications A dietary supplement for preventing or treating calcium deficiency. Commonly used to relieve heartburn and indigestion.
Food Industry Acts as a calcium fortifier and is used as a preservative or colorant (E170).
Environmental Applications Used to soften water and remove impurities.

The formation and transformation mechanism of calcium carbonate in water

Takeshi Ogino , Toshio Suzuki , Kiyoshi Sawada

, Geochimica et Cosmochimica Acta Volume 51, Issue 10 , October 1987, Pages 2757-2767

Highly supersaturated solutions of Ca2+ and CO2−3 ions rapidly precipitate amorphous calcium carbonate, ACC, the logarithmic thermodynamic solubility product of which is about −6.0 at 25°C. The ACC initially formed is transformed to a mixture of several crystalline calcium carbonate polymorphs within several minutes.

The mechanism of the thermal decomposition of calcium carbonate

A.W.D. Hills

, Chemical Engineering Science Volume 23, Issue 4 , June 1968, Pages 297-320

The decomposition of single sintered spheres of calcium carbonate has been investigated using a thermo-balance, modified to allow the simultaneous measurement of the temperature and weight of a decomposing sample. It has been shown that the decomposition reaction takes place on a definite boundary between the undecomposed carbonate, and the layer of porous lime formed outside it.

A hydrated crystalline calcium carbonate phase: Calcium carbonate hemihydrate

Z Zou, WJEM Habraken, G Matveeva, ACS Jensen

, Critical Reviews in Toxicology Volume 43, 2013 - Issue 4

It is proposed that Mg2+ ions in solution inhibit the dehydration of ACC and control the hydration level of the crystalline phases. The discovery of this hydrated crystalline calcium carbonate phase emphasizes the importance of amorphous precursors and Mg2+ in controlling the crystallization pathways of calcium carbonate.
