Calcium carbonate is widely used as an oral phosphorus binder to control hyperphosphatemia in children on maintenance hemodialysis. Intestinal calcium absorption may induce hypercalcemia, particularly if calcitriol is given simultaneously.
Calcium carbonate is a chemical compound , with the chemical formula Ca C O 3 . It is a common substance found as rock in all parts of the world, and is the main component of shells of marine organisms, snails, and eggshells. Calcium carbonate is the active ingredient in agricultural lime, and is usually the principal cause of hard water. It is commonly used medicinally as a calcium supplement or as an antacid .
This is probably the most ‘inorganic’ compound that be found in any toothpaste, just to give that abrasion feel as you brush your teeth. In no way should you of course, swallow the toothpaste just because it’s a toothpaste made of natural ingredients.
Calcium carbonate has two major crystalline forms—two different geometric arrangements of the calcium ions and carbonate ions that make up the compound. These two forms are called aragonite and calcite. All calcium carbonate minerals are conglomerations of various-sized crystals of these two forms, packed together in different ways and containing various impurities. The large, transparent crystals known as Iceland spar, however, are pure calcite.
