  skos:definition "Le carbonate de calcium (CaCO3) est composé d'ions carbonate (CO32-) et d'ions calcium (Ca2+). Il est le composant majeur des roches calcaires. Le carbonate de calcium cristallise naturellement sous deux formes principales : l'aragonite et la calcite. Lors des processus de cristallisation, il peut se présenter sous forme de colloïde contenant de fins cristaux de formes plus stables. (Adapté de : <a href=\"https://fr.wikipedia.org/wiki/Carbonate_de_calcium\">https://fr.wikipedia.org/wiki/Carbonate_de_calcium</a>)"@fr, "Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of eggshells, snail shells, seashells and pearls. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale.
