Calcium chloride is a white crystalline chemical compound with the formula CaCl2, widely used for its versatile properties in various industries. It is a highly hygroscopic substance, meaning it readily absorbs moisture from the air, making it effective for dust control on roads and as a de-icing agent to prevent the formation of ice on roadways in cold climates. Calcium chloride also finds application in the food industry as a food additive, primarily as a firming agent in canned vegetables and as a calcium source in certain food products. In addition to its industrial and culinary uses, it is employed in concrete production to accelerate the setting time of cement and in drilling fluids for oil and gas well drilling. Its ability to control moisture, lower freezing points, and serve as a calcium supplement underscores its importance across multiple sectors.
Calcium Chloride 94% is an ionic compound of calcium and chlorine. It can be produced either directly from limestone or as a by product of the Solvay process. It is hygroscopic in nature and behaves as a typical ionic halide.
Chemical Appearance
Calcium Chloride 94% is a crystalline white solid salt at room temperature. It is highly soluble in water and is deliquescent.
Calcium chloride is a chemical substance composed of Cl and Ca elements, with the chemical formula CaCl2, slightly bitter. It is a typical ionic halide, which is white, hard fragments or particles at room temperature. Its common applications include saline water used in refrigeration equipment, road ice melting agents, and desiccants.
Calcium chloride is used in salt water, road deicing agents, and desiccants used in refrigeration equipment. Due to its tendency to absorb water and deliquescence in the air, anhydrous calcium chloride should be stored in a sealed container. Calcium chloride and its hydrates and solutions have important application value in various fields such as food manufacturing, building materials, medicine, and biology.
Anhydrous calcium chloride is a commonly used dehydrating agent and drying agent in industrial production and laboratories (but cannot dry ammonia, hydrogen sulfide, and alcohol). It is mainly used for drying gases, petroleum, organic solvents, etc. Inorganic industry uses it as a raw material for making metallic calcium and various calcium salts. Calcium chloride is also used as a sizing agent, water purifier, antifreeze agent, food preservative, and road cleaning agent for textiles.
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
