Appeance:
Pellet copper sulphate:
Bright blue color, even pellet, fine mobility, dry and not agglomeration, for long-term storage.
Powder copper sulphate:
Even mixing, fine mobility, easy to assimilate.
It doesn't ooze or agglomerate in moist or high-temperature environment, so it is suitable for a long-term storage and transportation by sea.

Packing
1. Packed in laminated plastic-lined plastic woven bags of 25 Kgs net each,40bags stacked in a jumbo bag, 20MT per 20’FCL.
 2. Packed in PE bags of 25 Kgs net each,40bags stacked in a jumbo bag, 20MT per 20’FCL.
Characteristics
Small blue and clean crystal,density:2.284g/cm3,soluble in water and diluted acetic acid. The solution appears as weak acidity.It will be effloresces slowly in dry air, and its surface will become white powder substance.It will lose four crystal water when heated to 110℃,and will be changed into white copper sulfate anhydrous which is easy to absorb water when the temperature is higher than 150℃
Applications
It is used as an ionic additive for copper sulfate plating and acidic copper plating at wide range of tempretures for superior brightness. It is mainly used in the fields of science research., chemical reagent and IT industry because of our impurities such as Fe,Ca,Pb,As, Co,Ni are lower than the national standard GB665-88(chemical reagent grade).
