Calcium carbonate is an inorganic salt primarily used to manage and treat low calcium conditions, GERD, CKD, and other indicated conditions. Calcium carbonate is classified as a calcium supplement, antacid, and phosphate binder. This activity outlines the significant indications, actions, and contraindications for calcium carbonate as a ...

8.5 Calcium carbonate. Calcium carbonate is found in three forms: calcite, aragonite, and the very rare vaterite. Calcite is the most stable polymorph with hexagonal structure, and can have a great variety of particle morphologies. Aragonite, which evolves spontaneously to calcite, is orthorhombic.

This coralline calcium carbonate is used for years to treat bone defects in dentistry and orthopedics in a converted form as hydroxyapatite and in its natural aragonite form. Because of its application as bone graft material in form of eggshells or coralline component, calcium carbonate is another investigated substance in this study [11,6,9,12 ...
