Product Description
Product: Calcium Chloride
Molecular Formula: CaCl2
CAS No.: 10043-52-4
Calcium chloride is an inorganic salt, which exists as solid or liquid. Solid calcium chloride is a white, crystal substance in the form of flake, granule, pellet or powder. With different crystallized water contents, it can be dihydrate or anhydrous. Liquid calcium chloride is a colorless, clear solution. As calcium chloride has such properties as quick dissolving, exothermic ability, attracting moisture from the air and surroundings, dissolving at very low temperature, it is widely used in snow & ice melting, dust control, oil & gas drilling, moisture-absorbing, etc.
