Chemical Name: magnesium carbonate
Molecular Formula: 4MgCO3·Mg(OH)2·5H2O
CAS: 39409-82-0
Character: In normal temperature, it’s with three hydrates. Light one is white, easily fragile or loose white powder. Odorless. The 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 cannot be soluble in ethanol but it could be soluble in olefine acid with sparkling.
Usage: It's used as drier, color fixatives, antitackiness agent, carrier, swelling agent, acidity regulator.
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.
Storage and Transport: It should be stored in a dark, dry and ventilate warehouse, kept away from water and moisture; unloaded with care to avoid damage. Furthermore, it must be stored separately from poisonous substances.
