Inquiry
  Post Date: Jun 23,2015
  Expiry Date: Dec 20,2015
  Detailed Description: Cas No. :7446-20-0 Molecular formula:ZnSO4.H2O

CAS NO.: 7446-19-7

Packaging: In 25kg or 50kg plastic woven bags within PE liner.

Property: white crystal power, deliquescent in the air, soluble in water, slightly soluble in alcohol, 
insoluble in acetone.

Usage: Mainly used as the raw material for zinc barium and other zinc salts, 
auxiliary materials for viscose fiber and Vinylon fibers. In agriculture, 
it can be used to trace element fertilizers. Also used in electroplating, flotation, 
to prevent the fruit tree seedlings disease and circulating cooling water treatment.
