Molecular formula  ZnSO₄ 7H₂O
Molecular weight    287.56
Physical and chemical property
White or slight-yellow crystal, loose and no agglomeration, easy soluble in water and slightly dissolvable in alcohol and glycerol, insoluble in liquid ammonia and ketone, tending to lose water molecules of hydration in dry air and become white powder appearance. When the temperature is 280℃, it will become no water substance and lose all crystal water. When the temperature is above 500℃, it will decompose.
Relatively density: 1.975
Melting point: 100℃
Use
It is necessary microelement and additive for the feed in stockbreeding and fishery and it can prevent disease, urge up growth and improve nutrition quality.
Characteristic and function

1. It can be used as the feed additive and its cost is lower compared with zinc material and units so it can reduce the cost of feed.
2. As feed additive, it can enhance nutrition quality and prevent disease.

Packaging and transportation
