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 dehydrate 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 According to the content of crystal water in calcium chloride: (1). Calcium chloride dehydrate a. Calcium chloride flake dehydrate 74%min; 77%min; b. Calcium chloride granule/pellet dehydrate 74%min; 77%min (2). Calcium chloride anhydrous a. Calcium chloride powder anhydrous 94% min b. Calcium chloride pellets anhydrous 94%-97% min according to grade: (1). Calcium chloride industrial grade (2). Calcium chloride food grade
