Calcium carbonate is a chemical compound with the formula Ca CO 3.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 pearls and the shells of marine organisms, snails, and eggs.Calcium carbonate is the active ingredient in agricultural lime and
Calcium carbonate is an eco-friendly material widespread in nature and continuously reformed through natural water cycles (Vergaro et al., 2019). Porous calcium carbonate has been proposed as an excipient to improve the dissolution of poorly soluble drugs as well ( Trofimov et al., 2018 , Preisig et al., 2014 , Yang et al., 2017 , Borrego
Dec 03, 2019· What is calcium carbonate? Calcium is a mineral that is found naturally in foods. Calcium is necessary for many normal functions of the body, especially bone formation and maintenance. Calcium carbonate is used to prevent or to treat a calcium deficiency. There are many brands and forms of calcium carbonate available.
