Anwendungen

Magnesium carbonate hydroxide hydrate is used as drier, color ficatives, anticaking agent, carrier, swelling agent, acidity regulator. Magnesium carbonate is the production of magnesium oxide by calcining. Magnesite and dolomite minerals are used to produce refractory bricks. MgCO3 is also used in flooring, fireproofing, fire extinguishing compositions, cosmetics, dusting powder, and toothpaste. Other applications are as filler material, smoke suppressant in plastics, a reinforcing agent in neoprene rubber, a drying agent, a laxative to loosen the bowels, and color retention in foods. In addition, high purity magnesium carbonate is used as antacid and as an additive in table salt to keep it free flowing.

Bemerkungen

It should be stored in a dark, dry and ventilative warehouse, kept away from water and moisture
