Product Aliases

The common aliases of calcium chloride include calcium dichloride, chlorocalcite, and calchlor. These aliases are frequently used in different industrial fields and international trade communications, helping importers quickly identify the product in various scenarios.

Product Properties and Physical Characteristics

Calcium chloride is a white or off-white inorganic compound, odorless and slightly bitter in taste. It has strong hygroscopicity and is easy to deliquesce when exposed to air, so it needs to be stored in sealed packaging to avoid moisture absorption. It is highly soluble in water, and a large amount of heat is released during dissolution; its solubility in water increases with the rise of temperature, with a solubility of 59.5g/100g water at 0℃ and 159g/100g water at 100℃. It is also soluble in methanol, ethanol and other polar solvents but slightly soluble or insoluble in low-polarity solvents such as ether.

The physical characteristics of calcium chloride vary slightly according to its form: powder calcium chloride has fine particles and good fluidity; granular calcium chloride has uniform particle size and is not easy to agglomerate; flake calcium chloride has a sheet structure and convenient storage and transportation; prill calcium chloride has a spherical shape and strong stability. Its melting point is 772℃, boiling point is 1600℃, and density is 2.15g/cm³, showing excellent thermal stability under normal use conditions.

Product Applications

Calcium chloride has a wide range of applications in industrial, food, pharmaceutical, and construction fields, making it a high-demand product in international trade:

Drying and Dehydration: As a multi-purpose desiccant, it is used for drying gases such as nitrogen, oxygen, hydrogen, and carbon dioxide, and as a dehydrating agent in the production of alcohols, esters, and ethers. It is also used as an air moisture absorbent in household dehumidifiers and medical dressings.

Road Deicing and Anti-icing: It can reduce the freezing point of water, so it is widely used as a road deicer and anti-icing agent in cold regions, effectively preventing road freezing and ensuring traffic safety. It is also used as a defogging agent in ports.

Construction Industry: As an excellent concrete antifreeze, it can accelerate the hardening speed of concrete and improve the cold resistance of building mortar, suitable for construction projects in low-temperature environments. It can also provide appropriate moisture for concrete due to its hygroscopicity.

Food Industry: Approved as a food additive (E509), it is used as a calcium fortifier, curing agent, chelating agent, and desiccant in food processing, such as in vegetable and fruit cans, tofu making, and beer brewing.

Other Fields: It is used as a protective agent and refining agent in aluminum-magnesium metallurgy, a filter aid in wastewater treatment, an additive in lubricants, and a heat source in self-heating cans and heating pads. It is also a raw material for the production of other calcium salts.

Product Certification and MSDS

The calcium chloride product has passed REACH registration, complying with the EU's chemical management regulations and meeting the import requirements of European and American markets. For the safety of use and transportation,MSDS download service is provided, which contains detailed information on product hazards, safety precautions, first-aid measures, and environmental protection, helping importers complete customs clearance and safe use procedures smoothly.

FAQ

Q1: What is the shelf life of calcium chloride when properly stored?

A1: When stored in a cool, dry, and sealed warehouse, away from moisture and oxidants, the shelf life of calcium chloride is 24 months. If the inner packaging is damaged and moisture absorption occurs, it should be processed in time to avoid affecting the product quality.

Q2: Can calcium chloride be mixed with other chemicals during transportation and storage?

A2: It is not recommended to mix calcium chloride with oxidants, harmful and toxic substances, and other pollutants during transportation and storage to prevent chemical reactions that affect product quality or cause safety hazards. It should be stored separately from ethanol and ammonia, as it will form complexes with them.

Q3: Are all forms of calcium chloride consistent in chemical properties and application effects?

A3: The chemical properties of different forms of calcium chloride are basically the same, and their application effects are consistent in the same field. The choice of form mainly depends on the specific use scenario and operation requirements-for example, powder form is suitable for small-scale drying, while granular and flake forms are more suitable for large-scale industrial applications and long-distance transportation.
