Description
Calcium carbonate appears as white, odorless powder or colorless crystals. 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. Precipitated calcium carbonate (CAS: 471-34-1) is produced industrially by the decomposition of limestone to calcium oxide followed by subsequent recarbonization or as a by-product of the Solvay process (which is used to make sodium carbonate). Precipitated calcium carbonate is purer than ground calcium carbonate and has different (and tailorable) handling properties.;Limestone is an odorless, white to tan powder.;Limestone (calcium carbonate) that has been recrystallized by metamorphism and is capable of taking a polish.

Application
Calcium Carbonate Nanoparticles serve an important role across a variety of applications due to their unique properties. These nanoparticles are derived from calcium carbonate, a naturally occurring white solid that is only sparingly soluble in water but readily dissolves in acids. Historically used for neutralizing, cleaning, and polishing, the fine particles of calcium carbonate are essential in numerous industrial processes. They are crucial in the production of building materials like cement and glass, the creation of quicklime, and numerous calcium compounds. Beyond traditional uses, the nanoscale form of calcium carbonate offers enhanced features such as higher purity and more uniform particle sizes, opening doors to advanced applications in sectors like paints, plastics, textiles, adhesives, and even cosmetics. Serving as mild abrasives, stabilizers, and fillers, these nanoparticles contribute to the improvement of product durability, aesthetics, and performance. Moreover, in medical applications, calcium carbonates are utilized as calcium supplements and phosphate-binding agents, with the nanoscale variant providing potential benefits in terms of absorption and digestive tolerance.
