Magnesium carbonate is an inorganic chemical compound. Its chemical structure has a molecular formula (MgCO3). Its anhydrous form (free from water) is called magnesite also, di, tri, and even pentahydrates having other chemical properties different from each other. Its other names are magnesia alba, Magnesium as well as Carbonate salt. It is soluble in acid (anhydrous). Practically insoluble in ethanol and acetone. It occurs naturally as magnesite minerals thus the main source of elemental magnesium. It reacts with acids. Various base forms of magnesium exist mainly as minerals.
USES AND APPLICATIONS FOR Magnesium Carbonate
It is used in numerous industrial applications like:-
- It is used in pharmaceuticals.
- It is used in the treatment of indigestion and dietary supplementation.
- It is used in toothpaste and cosmetics.
- It is generally utilized as a drying agent (most often referred to as Chalk) for mountain climbing and weight-lifting.
- It is mainly used in fire extinguishing composition, fireproofing, and even flooring.
- It is used in food as an anticaking agent, color retention, and drying agent.
- High purity magnesium is used as an Antacid.
- It is used in pesticides as well as in pet care products.
Magnesium Carbonate can be produced in the laboratory by the chemical process of Magnesium Chloride and Sodium Bicarbonate. Also, it is obtained by mining the mineral magnesite.
- Magnesium Carbonate reacts with aqueous acids.
- Insoluble in ammonia and alcohol etc.
- It decomposes at high temperatures to produce magnesium oxide (Calcining Process).
- It is odorless, light, and bulky white powder.
- It is a colorless crystal.
- Its refractive index is 1.5a and 1.7b
- It is also stable in the air.
