Calcium Chloride Anhydrous

Calcium Chloride Anhydrous is the water-free form of calcium chloride, an ionic salt with CAS Number 10043-52-4. It appears as a white, odorless, hygroscopic crystalline powder or granules.

Calcium Chloride Anhydrous, a versatile, highly hygroscopic inorganic compound widely used for de-icing, dust control, concrete acceleration, oil & gas drilling, food processing, and as a powerful drying agent.

Technical Specifications

Package & Storage

Net weight 25kg/1000kg bag.
Store in a cool, dry, tightly sealed container away from moisture to prevent caking and deliquescence.

Benefits of Calcium Chloride Anhydrous

Superior Hygroscopicity:
Absorbs moisture efficiently, ideal for drying and dust suppression.

Freezing Point Depression:
Lowers the freezing point of water more effectively than sodium chloride, enabling de-icing at lower temperatures.

Heat Generation:
Dissolves exothermically in water, providing rapid ice-melting action.

Ionic Strength & Stabilization:
Enhances drilling fluid density and shale stability in oil & gas operations.

Accelerates Setting:
Speeds up concrete hydration, especially in cold weather.

Applications and Uses of Calcium Chloride Anhydrous

De-Icing and Snow Removal:
Effective at temperatures as low as -50°C, it melts ice faster and lasts longer than traditional rock salt.

Dust Control and Road Stabilization:
Its moisture-absorbing ability keeps unpaved roads, construction sites, and mining areas dust-free by retaining humidity in the soil.

Concrete Acceleration:
Reduces setting time and improves early strength development in cold-weather concreting.

Oil & Gas Industry:
Used in drilling, completion, and workover fluids to increase density and stabilize boreholes.

Food and Beverage Processing:

Serves as a firming agent in canned vegetables/fruits, cheese production, and as a processing aid.

Industrial Desiccant and Drying Agent:
Removes moisture from gases, liquids, and packaging environments.

Frequently Asked Questions (FAQs)

Q: What is the CAS number for Calcium Chloride Anhydrous?
A: The CAS Number is 10043-52-4.

Q: Is Calcium Chloride Anhydrous safe for food use?
A: Yes, it is affirmed when used in accordance with Good Manufacturing Practices (GMP) as a firming agent, pH control agent, and more.

Q: Why is it called “anhydrous”?
A: “Anhydrous” means it contains no water of crystallization, unlike dihydrate or hexahydrate forms, giving it stronger moisture-absorbing properties.

Q: How should Calcium Chloride Anhydrous be stored?
A: Store in airtight, moisture-proof containers in a cool, dry place. Exposure to air causes it to absorb moisture and potentially cake or liquefy.

Q: What makes it effective for de-icing?
A: It lowers the freezing point of water significantly and releases heat upon dissolving, melting ice faster and at lower temperatures than sodium chloride.

Q: Can it be used as a desiccant?
A: Yes, its high hygroscopicity makes it one of the most effective drying agents for industrial gases, solvents, and packaging.

Q: Is Calcium Chloride Anhydrous corrosive?
A: Concentrated solutions can be mildly corrosive to some metals (e.g., aluminum, brass). Rinse equipment after use.
