kálciumkarbonát

Kálciumkarbonát, also known as calcium carbonate, is a common chemical compound with the formula CaCO3. It is a white, odorless powder that is insoluble in water but soluble in acids. Kálciumkarbonát is a naturally occurring substance found in rocks like limestone, marble, and chalk. It is also a major component of seashells, pearls, and eggshells.

In nature, kálciumkarbonát is formed through various geological processes. It can precipitate from water containing dissolved calcium ions and carbonate ions, often facilitated by the activity of marine organisms that extract these ions to build their shells and skeletons. Over geological time, the accumulation of these organic materials forms vast deposits of calcium carbonate rocks.

Kálciumkarbonát has numerous applications across various industries. It is widely used as a building material, particularly in the form of limestone and marble for construction and decoration. In agriculture, it is employed as a soil amendment to neutralize soil acidity and provide essential calcium for plant growth. The food industry utilizes kálciumkarbonát as a food additive (E170) for purposes such as an anticaking agent, a nutrient supplement, and a colorant. It is also a key ingredient in antacids, where it neutralizes excess stomach acid. Furthermore, kálciumkarbonát is used in the production of paper, plastics, paints, and pharmaceuticals. Its versatility and abundance make it one of the most important industrial minerals.
