1、Chemical Name: MAGNESIUM CARBONATE 2、Molecular Formula: xMgCO3?yMg(OH) 2?nH2O 3、Molecular Weight: --- 4、CAS: 39409-82-0 5、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. 6、Usage: It’s used as drier, color ficatives, anticaking agent, 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、Storage and Transport: It should be stored in a dark, dry and ventilative warehouse, kept away from water and moisture; unloaded with care to avoid damage. Furthermore, it must be stored separately from poisonous substances.
