Anhydrous Calcium Chloride

Calcium Chloride Anhydrous

Properties:

Chemical Name: Calcium chloride anhydrous

Molecular Formula: CaCl2

Molecular Weight: 110.98

CAS No.: 10043-52-4

Physical chemical properties: White porous granular, honeycomb, odorless, bitter taste. The relative density is 2.15 (25 ). Melting point 782 . Boiling point above 1600 , hygroscopicity strong.

Application:

Deicing and freezing point depression: By depressing the freezing point of water, calcium chloride is used to prevent ice formation and is used to deice.

Road surfacing: The second largest application of calcium chloride exploits its hygroscopic properties and the tackiness of its hydrates. A concentrated solution keeps a liquid layer on the surface of dirt roads, which suppresses formation of dust.

Oil/gas Drilling fluid:  It is used in drilling mud to cool and lubricate the bit and to remove  cuttings from the hole. Calcium Chloride helps add density to the mud to  overcome formation pressures and keep oil, gas, and water in place.  Calcium Chloride inhibits clay and shale hydration, adds needed weight  to overcome formation pressure, aids in carrying cuttings to the  surface, and is easily diluted from more concentrated solution.

Water treatment: Calcium chloride is used to increase the water hardness in swimming pools.
