Product Description:
Calcium chloride is a type of inorganic compound consisting of calcium (Ca²⁺) and chloride (Cl⁻) ions. Its chemical formula is CaCl₂. This compound can be found in two forms: anhydrous (CaCl₂) or hydrate form (e.g., CaCl₂ · 2H₂O, CaCl₂ · 6H₂O). Typically, it appears as colorless crystals or white particles/powders.
When mixed with water, calcium chloride dissolves readily due to its high solubility and remarkable hygroscopic properties, meaning it tends to absorb moisture from the surroundings. While it occurs naturally in sources like seawater, salt lakes, and certain minerals, industries often acquire calcium chloride through processes like reacting limestone with hydrochloric acid or obtaining it as a byproduct of the Solvay process during alkali production.
Features:
Physical and Chemical Properties
Strong hygroscopicity: It easily absorbs moisture and even deliquescence into liquid, widely used as a desiccant.
High solubility: It has extremely high solubility in water (about 74.5 g/100 mL at 20 ℃), and the dissolution process releases heat violently.
Low freezing point: The freezing point of an aqueous solution is significantly lowered (such as the freezing point of a 30% solution is about -50 ℃), which is suitable for snow melting agents.
Melting point/boiling point: Anhydrous calcium chloride has a melting point of approximately 772 ℃ and a boiling point greater than 1600 ℃.
Complexation: Can form complexes with ammonia, ethanol, etc. (such as CaCl ₂ · 4NH ∝).
Chemical activity
Reacts with sulfates and carbonates to form precipitates (such as CaSO4 and CaCO3).
Can react with oxides such as silica at high temperatures.
safety
High concentration solutions are corrosive to metals and concrete, and should be used with caution.
Applications:
Roads and Transportation
Snow melting agent: Calcium chloride lowers the melting point of ice and snow, quickly melting road snow.
Dustproof agent: Calcium chloride sprayed on dirt roads to suppress dust by utilizing its hygroscopicity.
Industrial Sector
Desiccant: Calcium chloride is used for drying gases such as air, nitrogen, hydrocarbons, or industrial equipment to prevent moisture.
Concrete additives: Calcium chloride accelerates cement hardening and improves early strength.
Oil extraction: Calcium chloride is used to prepare high-density drilling fluid to stabilize oil well pressure.
Food and Medicine
Food additives: Calcium chloride is used as coagulants (such as tofu production), preservatives, or electrolyte supplements in sports drinks.
Medical use: Calcium chloride is used to treat hypocalcemia, as an ingredient in anti-allergic injections, or as an anticoagulant for blood banks.
Environmental Protection and Chemical Industry
Wastewater treatment: Calcium chloride aids in the sedimentation of pollutants such as phosphates and fluorides, and adjustment of pH value.
Refrigeration system: Calcium chloride is used as a low-temperature refrigerant, such as in a cooling bath.
Laboratory reagents: Calcium chloride is used for drying gases, catalyzing reactions, or preparing other calcium salts.
Other Purposes
Agriculture: Calcium chloride in foliar fertilizers supplements calcium elements and regulates soil pH.
Plastic industry: Calcium chloride is used as an additive to improve material properties.
