1、Chemical Name:  Manganese Sulfate

2、Molecular Formula : MnSO4·H2O

3、Molecular Weight: 169.02

4、CAS: 7785-87-7

5、Character: It is pale pink monoclinic system coarse crystal, odorless. Relative density is 2.95. It starts to lose crystal water when heated to above 200℃. It almost loses all crystal water when above 280℃. And to 700℃, it changes to anhydrous melts. It starts to decompose when heated to 800℃ and black insoluble Mn3O4 is left.  It completely decomposes at the temperature of 1150℃. It is freely soluble in water, but is insoluble in alcohol.

6、Usage: Nutritional Supplement (Manganese Fortifier)

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.
