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 350ºC. It's stable in the air. When heated to 700ºC, 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.

Packing: 25kgs paper bag or customized package.

Q What is the purpose of magnesium carbonate?

Description: What is magnesium carbonate used for? Where can magnesium carbonate be used?

Answer Magnesium carbonate can be used as a flour treatment agent in my country. The maximum use amount is 5.0g/kg; the maximum use amount in wheat flour is 1.5g/kg (in flour). 
; Used in the manufacture of drugs for neutralizing gastric acid and treating duodenal ulcer; used in medicine and rubber industry; used in the manufacture of magnesium salts, magnesium oxide, fireproof coatings, inks, glass, toothpaste, rubber fillers, etc., used in food 
Flour improver, bread leavening agent, etc.

Q How is the water solubility of magnesium carbonate?

Description: What is the solubility of magnesium carbonate in water?

Answer The water solubility of magnesium carbonate is: g MgCO3/100g solution at CO2 pressure, kPa, 18°C: 3.5 (203), 4.28 (405), 5.90 (1010), 7.49 (1820), 7.49 (5670); at 0 
°C 8.58 (3445), at 60°C 5.56 (3445); soluble acids; insoluble alcohol [HAW93] [KIR81]

Q Is magnesium carbonate precipitated?

Description: Is magnesium carbonate precipitated?

Answer Magnesium carbonate has relatively low solubility in water and is slightly soluble in water. After adding a small amount of magnesium carbonate to the solution, there will be no solid remaining after stirring, but a slight excess will cause precipitation. Magnesium carbonate will be in a weakly acidic solution. 
Will decompose to produce carbon dioxide. 
Even magnesium carbonate solution will produce magnesium hydroxide and carbon dioxide when heated (softening of hard water)
