Zinc Sulfate Heptahydrate appeared as colorless orthorhombic prism crystal. It is easily soluble in the water and dissolve in the alcohol and Glycerol slightly. It is used as raw material for production of lithopone and in synthetic fiber industry, zinc plating, in trace element fertilizer, feed additive, micronutrient product, electroplating and flotation of ores, etc.

It is packed in 25 kg / 1000 kg plastic woven bags with polyethylene inner bags.

It should be stored in a cool, dry and ventilated place to avoid efflorescence and moisture absorption. Preventing the goods from raining and solarization in the course of transportation, and avoiding breathing dust and contacting with eyes when handling.
