Anwendungen

Calcium carbonate is used in the purification of iron, refining of sugar from sugar beet, and flue gas desulfurization applications in fossil fuel power stations. It is used in blackboard chalk, printing and writing paper, paints, plastics, PVC cables, polypropylene compounds, thermosetting resins, adhesives, sealants, and decorating fillers. It is an abrasive, and an ingredient in many glazes. It is also used in the pharmaceutical industry as an inert filler for tablets and other pharmaceuticals. It is used as a base in many organic reactions.

Bemerkungen

It is stable under normal conditions. Hygroscopic in nature. In the presence of carbon dioxide and water, it gets converted to calcium hydrogen carbonate, which has good solubility in water.
