Calcium Chloride (CaCl2)
Basic introduction of the product: Calcium Chloride is an inorganic salt composed of calcium and chlorine. It is a white, crystalline solid that is highly soluble in water and is hygroscopic, often encountered as a hydrated solid (e.g., dihydrate or hexahydrate). Due to its properties, particularly its ability to lower the freezing point of water and act as a drying agent, it has a vast range of industrial, food, and medical applications.
Synonyms: Calcium dichloride, E509 (food additive)
Chemical Formula: $CaCl_2$ (Anhydrous form)
CAS NO.: 10043-52-4 (Anhydrous form)
8-digit HS Code: 28272000
Industries Used In:
- Construction: Used as a concrete accelerator to speed up the setting time.
- Oil and Gas: Employed in drilling muds, completion fluids, and workover fluids to increase density and control pressure.
- Food and Beverage: Used as a firming agent (for tofu, canned vegetables, pickles), an electrolyte, and a preservative.
- Road Maintenance: Primary component in de-icing salts and for dust control on unpaved roads.
- Refrigeration/Chemistry: Used in brine solutions for refrigeration plants and as a desiccant (drying agent) in laboratories and shipping containers.
- Medical: Used intravenously to treat hypocalcemia (low calcium levels) and hyperkalemia (high potassium levels).
Application or Usage: Primarily used for de-icing roads and sidewalks, dust control, as a desiccant (moisture absorber), and as a firming agent in the food industry.
