1、Chemical Name: Magnesium Carbonate

2、Molecular Formula: xMgCO₃·yMg(OH) ₂·zH₂O

3、Molecular Weight: ---

4、CAS: 39409-82-0

5、Character: Light one is white, friable masses or bulky, white powder, odorless. Relative density is 2.2. Melting point is 350. It’s stable in air. When heated to 700, it decomposes to carbon dioxide and magnesium oxide. It’s almost insoluble in water, but it imparts a slight alkaline reaction. It is insoluble in ethanol, but dissolves, with effervescence, in dilute acids.

6、Usage: It’s used as nutrient, flour treatment agent, anti-caking agent and leavening agent. It could be used in wheat powder and gum ingredients.

7、Packing: It is packed with polyethylene bag as inner layer, and a compound plastic woven bag as outer layer. The net weight of each bag is 25kg.

8、Storage and Transport: It should be stored in a dry and ventilative warehouse, kept away from heat and moisture during transportation, unloaded with care so as to avoid damage. Furthermore, it must be stored separately from poisonous substances.
