to calcium carbonate ratio

Calcium carbonate CaCO3 - PubChem

Calcium Carbonate is the carbonic salt of calcium (CaCO3). Calcium carbonate is used therapeutically as a phosphate buffer in hemodialysis, as an antacid in gastric hyperacidity for temporary relief of indigestion and heartburn, and as a calcium supplement for preventing and treating osteoporosis.

Calcium Carbonate - an overview ScienceDirect Topics

Calcium carbonate (CaCO 3) is a substance widely used for various purposes, for example, as a filler and pigment material not only in paper, plastics, rubbers, paints, and inks but also in pharmaceutics, cosmetics, construction materials, and asphalts and as a nutritional supplement in animal foods (1).Besides the so-called ground calcium carbonate (GCC), which is milled from natural limestone ...

The effects of the Mg 2+ ion concentration and the ionic products of carbonate upon the induction time for the onset of precipitation and the different mineralogies of calcium carbonates were studied. It was shown that Mg 2+ ions delay the spontaneous precipitation of calcium carbonate from supersaturated solutions (e.g. seawater) with respect to calcium carbonate mineral to such an extent ...
