Product Description

 

Product Description

Magnesium carbonate is an inorganic compound with the chemical formula MgCO3, a molecular weight of 84.31, and a relative density of 3.037.
It appears as a white granular powder. It decomposes at 350°C and loses carbon dioxide at 700°C. It is slightly soluble in cold water and slowly soluble in acid. Its trihydrate is a colorless needle-shaped crystal with a melting point of 165°C and a relative density of 1.850.
Its pentahydrate is a white monoclinic crystal with a relative density of 1.73. It decomposes when heated in air.
A hydrate can be obtained by passing carbon dioxide into a magnesium salt aqueous solution while adding sodium carbonate.
The anhydrous form can be obtained by drying the hydrate at below 50°C.
 

Detailed Photos

1. Chemical Name : Magnesium Carbonate
 2. Molecular Formula : MgCO3
 3. Molecular Weight:86.32980
 4. CAS: 546-93-0
 5. Character: In normal temperature, it's with three hydrates. Lightone is white, easilyfragile 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.
 6. Usage: It's used as drier, color fixatives,antitackinessagent, carrier, swelling agent, acidity regulator.
 7. Packing:It is packed with polythene bag as the inner layer, and a compound plastic woven bag as the outer layer. The net weight of each bag is 25kg.
 8. Storageand Transport: It should be stored in a dark, dry and ventilate warehouse, kept away from water and moisture; unloaded with care to avoid Furthermore, it must be stored separately from poisonous substances.
