Exporting Pure Food Grade Additives White Magnesium Carbonate Powder MgCo3
Magnesium carbonate, the chemical formula MgCO3, is a white powdery inorganic compound containing magnesium. Magnesium carbonate is chemically stable, non-toxic, odorless, and non-flammable. Metathesis reaction with acid stronger than carbonic acid produces salts and carbon dioxide and other substances, insoluble in water, acetone and liquid ammonia. It is water-absorbing and oil-absorbing, so gymnastics, weightlifting and rock climbers often use magnesium carbonate to wipe their hands to keep their hands dry, but magnesium carbonate may cause skin allergies in some people. In addition, magnesium carbonate can also be used as gastrointestinal related drugs such as antacids and constipation drugs.
Character: In normal temperature, it’s with three hydrates. Light one is white, easily fragile or loose white powder. Odorless.
Relative density is 2.2. Melting point is 350℃. It’s stable in the air. When heated to 700℃, it will become magnesium oxide.
It’s hardly soluble in water, but it’ll bring a slight alkaline reaction.
It can not be soluble in ethanol but it could be soluble in olefine acid with sparkling.
